7 Biochemistry Lab Experiments that are Easier to Teach with Labster

You want the best biochemistry labs for your students. Maybe lesson planning is taking up too much time, you’re recycling the same labs over and over, or you’re a new teacher. Whatever the case, we’ve gathered 7 biochemistry lab experiments that you can teach your students. We’ve also matched accompanying virtual labs that can help teach some of the experiments.

• DNA/RNA Sequencing
• Gel Electrophoresis
• Antibodies & Antigens
• Blotting Methods
• Polymerase Chain Reaction (PCR)

ELISA stands for enzyme-linked immunosorbent assay. basic assay technique. Trying to capture a specific protein amongst thousands of types of proteins is like looking for a needle in a haystack, but it’s easier with this basic assay technique. Instructors can provide ELISA kits if budgets allow.

There are incubation times necessary with this method, so the collapsed time aspect of using a virtual lab is useful! Labster has an ELISA Virtual Lab where students can help a doctor quantify Factor IX protein, which is used for hemophilia drugs.

2.) DNA/RNA Sequencing

With the right equipment, DNA & RNA sequencing can be straightforward and easy. Fast and affordable sequencing matters, as it opens up a whole new world for biology/biochemistry research. There are a variety of ways to do sequencing, but they can be expensive - especially for a lab class. 

Labster has a few sequencing labs, one being RNA Extraction: Sample and purify mRNA from pigs where students can learn how to extract RNA from pig fat tissue samples and how to purify messenger RNA using magnetic beads.

3.) Nutrition

There’s a great deal of biochemistry research done in the field of nutrition such as understanding how food relates to cancer and how food can promote health. A CUNY lab exercise guide outlines some different hands-on labs instructors can do such as “The Microbiology of Milk and Food.”

Some concepts can be difficult to get across to students in a regular lab or through lecturing. That’s where our 3D animations and interactivity are most impactful. Labster has a Carbohydrates virtual lab where students can visualize and explore how carbohydrates are broken down by the digestive system and taken up into the bloodstream.

4.) Gel Electrophoresis

This technique is used to separate components of a mixture, often DNA, RNA, or proteins. Kits are available to do this experiment in the classroom if the budget allows for it. Virtual lab simulations are a cost-effective alternative Not only are they helpful for learning the technique itself, but also to visualize the components. 

In Labster’s Gel Electrophoresis virtual lab , students will solve a crime by using DNA fingerprinting to identify a thief. Students will use nucleic acid gel electrophoresis to separate and visualize DNA molecules and watch an animation to understand what happens inside the gel tank.

 5.) Antibodies & Antigens

Antibodies and Antigens can be difficult to teach but Labster has a free 3D animation video on “Antigen-Antibody Binding - Why are some blood types incompatible?” Utilizing videos, interactive simulations, lectures, and images help to differentiate teaching approaches and support students in learning these concepts. 

In Labster’s Antibodies virtual lab , learn about the concepts of antibodies and antigens, as well as the ABO and Rhesus blood grouping systems and their importance in blood transfusions. Then, they will help a young couple determine the potential risk for Rhesus disease in their unborn child.

Figure alt text: Tight antibody-antigen complex.

6.) Blotting Methods

Students need to use blotting methods to identify DNA, RNA, and other proteins. There are a variety of blots: Northern, Southern, Eastern, and Western (1). This technique can be done in the lab - but it is notoriously difficult at first. Practicing in a virtual lab helps students grasp the methods and understand how to analyze their results.

In our Western Blot virtual lab , students perform a western blot experiment to ultimately provide data and knowledge to identify a promising treatment for breast cancer.

7.) Polymerase Chain Reaction

Polymerase Chain Reaction (PCR) is used to amplify or make multiple copies of DNA (1). It can be expensive to run these labs as PCR labs are expensive and time-consuming. This is where virtual labs can help!

In the Polymerase Chain Reaction (PCR) simulation , students will be thrown right into a crime scene where a murder has taken place. After investigating the crime scene, their first task is to collect blood samples in the hope that the murderer has left traces of their DNA. A 3D animation will show the PCR experiment at the molecular level, illustrating the structure of DNA and its replication.

If you’re interested in teaching PCR in an approachable way, check out our PCR blog post . 

Questions for consideration?

• How could you incorporate these virtual labs into your teaching plans?
• Are these labs better as self-paced homework assignments or small-group collaboration in class?

Six Biochemistry Experiments for College Students

College instructors face few difficulties in finding lecture plans for teaching and doing biochemistry experiments, lesson plan sites offer an assortment of inexpensive and even free lesson plans for introducing biochemical concepts on which instructors can expand.

What is difficult for college biochemistry instructors to write are lesson plans for experiments that reinforce basic concepts in biochemistry while requiring students to articulate a hypothesis, test it in the lab, and articulate their results. Materials for teaching scientific facts are abundant, but materials for teaching scientific methods are hard to find.’

Modern Biology offers not just lesson plans but also complete lab materials for 25 experiment packages for biochemistry . Experiments from Modern Biology go beyond laboratory demonstrations.

Every experiment from Modern Biology trains students in the scientific method, not just scientific fact. And every experiment from Modern Biology includes test materials, standards, reagents, and incidental equipment for the exercise, no ordering or requisitioning is required.

EXP-102 Genetics and Sickle Cell Anemia: Students compare electrophoretic patterns in DNA from a person with normal hemoglobin with DNA from a person who has sickle cell traits. They are given an opportunity to test their own DNA for hemoglobin variants, This experiment can also serve as a springboard for discussion of social policy implications of molecular genetics.

EXP-106 Protein Fingerprinting: Students use electrophoresis to study the forms of lactate dehydrogenase found in different animals. They will note that the patterns in sheep and goat are similar to each other but very different from patterns in cow and horse.

Introduction to Molecular Genetics

Modern Biology’s Introduction to Molecular Genetics provides lesson plans and complete supplies for three experiments for 16 students for just $199.95.

EXP-301 Length of the DNA Molecule: Students determine the length of a sample of DNA by electrophoresis over an agarose gel, This experiment reinforces student understanding and practical skills for standardized ladder technique.

EXP-302 Restriction Nuclease Mapping of DNA: Bacteriophage lambda attacks E. coli DNA. In this experiment, students use restriction endonucleases EcoR1 and BamH1 to dissect bacteriophage lambda DNA to identify structures, sequences, and specific sites along the phage genome. Students gain a deeper understanding of DNA mapping strategies, complementary base-pairing of DNA, specificity of restriction endonucleases, and the structure of a viral genome.

EXP-304A Molecular Cloning: Students create a strain of E. coli that is resistant to ampicillin by introducing an ampicillin-resistance gene with a plasmid. They monitor the success of their procedure by growing E. coli in a medium including ampicillin.

How can you iso­late DNA in your own kitchen?

DNA is a mol­e­cule with a com­plex struc­ture that stores and pass­es on the ge­net­ic in­for­ma­tion of ev­ery liv­ing or­gan­ism on Earth. This sim­ple method of DNA ex­trac­tion is based on us­ing sur­fac­tants (soap) to de­stroy the lipid lay­ers of ba­nana cells’ mem­branes and nu­clei. Then, sodi­um ions from the ta­ble salt con­vert the DNA mol­e­cules from the de­stroyed cell ma­te­ri­al into a form that eas­i­ly pre­cip­i­tates from the cold iso­propyl al­co­hol.

What is kom­bucha? Just a drink, or …?

A SCO­BY (Sym­bi­ot­ic Cul­ture Of Bac­te­ria and Yeast) is a sym­bi­ot­ic or­gan­ism con­sist­ing of two com­po­nents: bac­te­ria and yeast, as the name sug­gests. The yeast fer­ments sug­ar to form al­co­hol and car­bon diox­ide, and acetic acid bac­te­ria ox­i­dize the al­co­hol and con­vert it into or­gan­ic acids. They grad­u­al­ly cre­ate a com­plex sys­tem that forms a thin film on the liq­uid's sur­face. As the bac­te­ria and yeast mul­ti­ply, the film thick­ens and ac­quires a char­ac­ter­is­tic jel­ly­fish-like shape. This gives it its name: Medu­somyces gi­se­vii. Be sure to wash the glass con­tain­er thor­ough­ly with a bak­ing soda so­lu­tion and rinse it with boil­ing wa­ter to pre­vent the for­ma­tion of the usu­al mold in­stead of SCO­BY.

How to use cab­bage to make pH in­di­ca­tor strips Red cab­bage con­tains pig­ments known as an­tho­cyanins. An­tho­cyanins can also be found in many fruits, veg­eta­bles, and berries, such as blue­ber­ries, red grapes, red onions, and so on. They change col­ors in ac­cor­dance with the acid­i­ty of their en­vi­ron­ment – a prop­er­ty that can help you de­ter­mine the pH of var­i­ous sub­stances around you! They turn red in acidic medi­ums such as vine­gar, pur­ple in weak­ly acidic and neu­tral medi­ums such as wa­ter, blue in weak­ly ba­sic medi­ums such as a so­lu­tion of bak­ing soda, and green, then yel­low in strong­ly ba­sic so­lu­tions such as drain clean­er.

How to test for vi­ta­min C at home

Many fruits and veg­eta­bles con­tain ascor­bic acid, also known as vi­ta­min C . It plays a key func­tion in bi­o­log­i­cal pro­cess­es in the body as a good re­duc­er and con­se­quent­ly a strong an­tiox­i­dant. It helps lim­it the im­pact of var­i­ous free rad­i­cals (ox­i­diz­ing agents that can cause mu­ta­tions and de­struc­tion in cells) on the or­gan­ism. Io­dine can be used to test veg­eta­bles and fruits for ascor­bic acid con­tent. Io­dine is an ox­i­diz­er, so when it re­acts with ascor­bic acid, it is re­duced to col­or­less io­dide ions.

How to ob­tain oxy­gen with the help of a plant

Here is an in­ter­est­ing and en­ter­tain­ing ex­per­i­ment that lies on the bor­der­line of two sci­ences – chem­istry and bi­ol­o­gy. You can eas­i­ly try it at home and amaze your friends and fam­i­ly. Pho­to­syn­the­sis is a com­plex chem­i­cal process in which light en­er­gy is trans­formed into chem­i­cal bond en­er­gy. More sim­ply, it is a process in which car­bon diox­ide and wa­ter are made into or­gan­ic sub­stances and oxy­gen un­der the in­flu­ence of light.

It is easy to prove the pres­ence of oxy­gen in the test tube. As oxy­gen is a gas that sup­ports com­bus­tion, all you have to do is low­er a smol­der­ing splint or match into the test tube, and it will im­me­di­ate­ly flare up.

Why do we need a so­lu­tion of bak­ing soda? As the car­bon diox­ide in the air dis­solves poor­ly in wa­ter, we can use car­bon­ates or bi­car­bon­ates, which by their na­ture are salts of car­bon­ic acid, to in­crease its con­cen­tra­tion.

Online lab work

Lab courses are one of the more complicated and difficult spaces to recreate or instruct through remote learning. Accept that the experience cannot be fully reproduced. Again, this is something that can be backward-designed. Start with the key learning objectives, and let that drive your decisions. If data analysis and critical thinking are part of your laboratory class outcomes, ensure they are built into the design of your lab course. AND let yourself to be creative and imperfect in design of the class. 

For lower level laboratories, are there simple experiments that can be conducted at home ? Depending on the number of students, mailed pH strips and household items could be used in a titration. Alternatively, consider finding a virtual simulation from the many collections on the Internet. We all know making solutions and buffers are the bane of biochemistry students - so think about designing learning activities on these subjects. 

Deep analysis of the literature is also an excellent way to build laboratory-related skills. Access a Journal of Biological Chemistry article and have the students review the methods sections - they can create presentations on various aspects of the methods of a few key papers and analyze the figures and results sections in a follow-up activity.  

Demonstrations are very valid when in a pinch. You could create a video of a technique and annotate the key steps of a western blot, an SDS-PAGE gel, or protein assay, or keep your teaching assistants employed by having them create videos or demonstrations. Include simple quizzes to keep students engaged. Walk students through an enzyme assay (use some of the resource links below if you don’t have your own) and videotape the assay being conducted - perhaps even do this live in a Zoom or WebEx chat or using the meeting features in your LMS.  Show the spectrophotometer as absorbance changes to talk about reactants and products. Pause and interact with the students, have them break out into groups (if your LMS allows) and make predictions on the experiment at hand. Then give them data sets to analyze. You might assign different data sets for different student groups, perhaps some that have a “flaw” and a follow-up repeated experiment.  

Biomolecular modeling is another interactive option. Using Chimera, PyMOL, Jmol or other visualization programs, you can design experiments where students are asked to model active sites, mutate amino acids, and consider the effects of a proposed mutation. There are RNAseq and protein mass spectroscopy databases that can be mined for hypothesis-driven experiences. Free programs exist to modify a PDB file and predict protein or ligand docking and energy minimization. Ask students to make predictions and conduct a virtual experiment based on a PDB structure. You can take advantage of many online tutorials in this area; there are several linked examples of these in the resource list. 

Shared Data Sets.  If you can use data sets from your prior labs, your personal research or that of a colleague, you can set up the kinds of virtual labs discussed here. Two specific examples linked below that focus on protein biochemistry are the Malate Dehydrogenase CURE Community and BASIL virtual protein lab groups. Both have plans for running parts of a semester in virtual format using existing shareable data. CourseSource and CURE.net are other possible sources to find labs with data to convert to this format.

You could also consider having students work on a grant proposal as an alternative to wet lab techniques. Students will gain experience in formulating hypotheses, experimental design, and literature analysis. They can learn about techniques and instrumentation that they might not have available to them in the laboratory.

Finally, think of all of the times you’ve taught a laboratory and wished there was more time to have students really think about their results… Why not have them go back and be critical in their analysis? Now you have time to do some very valuable teaching to the students.

Biochemistry in Everyday Life: Practical Applications and Examples

Biochemistry is a fundamental branch of science that explores the chemical processes and substances within living organisms. While its complex theories and laboratory experiments are often associated with academic settings, the principles of Biochemistry permeate various aspects of our daily lives, often in subtle yet significant ways. This blog aims to illuminate the practical applications and examples of biochemistry that we encounter in our everyday routines, shedding light on its relevance beyond the confines of scientific research. Understand its real-world implications, this guide will provide valuable insights into the vital role biochemistry plays in our daily lives.

One of the most recognizable applications of biochemistry in everyday life is in nutrition. The food we consume undergoes intricate biochemical processes within our bodies to provide energy, essential nutrients, and support bodily functions. For instance, carbohydrates are broken down into glucose, which serves as a primary source of energy for cells through the process of glycolysis. Similarly, proteins are digested into amino acids, which are crucial for building and repairing tissues, while lipids provide energy storage and insulation. Understanding these biochemical processes helps individuals make informed dietary choices to support their overall health and well-being.

Another prominent example lies in the realm of medicine and healthcare. Biochemistry underpins the mechanisms of various drugs and medications used to treat diseases and alleviate symptoms.
