Annotation -
Students will become familiar with basic biochemical methods. A method that has wide application in biochemistry is gel chromatography, students separate a protein from a mixture or determine the relative molecular mass of an unknown protein. Separation of proteins and determination of relative molecular mass is also performed by electrophoresis in polyacrylamide gel in the presence of SDS. Great attention is paid to the principles of working with enzymes: determination of specific enzyme activity, determination of enzyme affinity for the substrate, determination of maximum reaction rate, pH optimum, monitoring of the reaction time course and the influence of inhibitors and activators on the enzyme reaction. The presence of isoenzymes is demonstrated on the example of lactate dehydrogenase, which students separate in a polyacrylamide gel under native conditions and detect enzyme activity in the gel.

Syllabus -

1. Isolation of a protein - enzyme, determination of specific activity

2. Gel chromatography of proteins (separation, relative molecular mass determination)

3. SDS - polyacrylamide electrophoresis (determination of relative molecular mass of proteins)

4. Practical enzymology - kinetic characteristics, Michaelis constants, maximal reaction rate, pH optimum, activation and inhibition of enzymes, electrophoretic separation of isoenzymes and detection of the enzyme activity in gel

5. DNA manipulation (restriction analysis)

6. Oral presentation of one experiment

Learning outcomes -

The student will apply one of the protein isolation techniques, determine enzyme activity, measure protein concentration, and calculate specific activity.
The student observes the affinity of the enzyme for the substrate and determines Michaelis constant and maximum reaction rate.
The student determines the temperature and pH optimum of a selected enzyme, observes the effect of an inhibitor on enzyme activity, and observes the activity and individual isoforms of a selected enzyme after electrophoretic separation under native conditions.
The student uses gel chromatography to separate proteins, develops a calibration dependence of molecular weight on elution volume, determines the molecular weight of an unknown protein, and determines the distribution coefficient of a selected protein.
The student will perform electrophoretic separation of proteins in a polyacrylamide gel under SDS conditions and determine their relative molecular weight.
The student will measure DNA concentration, perform electrophoretic separation of DNA after restriction endonuclease cleavage, and compare suspect DNA samples to the crime scene.
