Description: The physical properties of proteins kit is a lab activity that enables students to investigate the physical properties of several different proteins. Students will learn about protein solubility and how it is affected by various parameters; including temperature, pH, salt and dielectric constant. They will understand about protein precipitation due to pH, high salt and in the presence of organic solvents and about protein denaturation as a result of high temperature. In addition, the kit will demonstrate how non-protein agents, such as detergents drastically alter the physical properties of protein molecules and as a result, understand the importance of detergents in protein solubilisation. This lab activity involves analysis of three different types of pure proteins and then students alter some of those properties with a detergent and re-examine physical properties of those proteins. Students are challenged to consider how physical properties of protein molecules can be exploited for purification and characterisation of proteins and apply their findings on a test sample of complex tissue extract.

Description: This lab activity is designed to demonstrate the different classes of protein molecules and their classification based on solubility. Students learn fractionation of soluble, insoluble membrane proteins, and cytoskeleton proteins from a tissue sample. The insoluble protein fraction is further fractionated into hydrophilic and hydrophobic membrane proteins. Cell membrane structure and the role of hydrophobic membrane proteins are considered. This lab activity also provides an opportunity to understand characteristics of various classes of detergents and the role of detergents in solubilisation of hydrophobic membrane proteins.

Description: In this experiment, students purify the restriction enzyme, <i>Eco </i>RI. This procedure utilised an ion exchange chromatograph step for <i>Eco </i>RI purification. Column fractions are assayed for the enzyme using Lambda DNA and digestion products are identified by gel electrophoresis. Fractions that contain <i>Eco </i>RI are identified and pooled. The total and specific activities are calculated. Recommended for advanced courses.

Description: This experiment introduces a simple method to determine protein subunit molecular weights using horizontal electrophoresis. As the protein standards and 'unknowns' are prestained, the separation of proteins can be observed during electrophoresis. Included in the experiment is protein-grade agarose, which provides an alternative to the use of polyacrylamide gels.

Description: Microarray technology allows scientists to screen large numbers of samples in one assay. This technology allows high-throughput screening of small samples and allows comparisons to be made between healthy and unhealthy tissues. In this experiment, students apply simulated DNA and RNA samples to a membrane to screen for positive and negative samples.

Description: Bovine spongiform encephalophathy (BSE), also known as Mad Cow Disease, is a neurodegenerative, fatal condition in cattle. Consuming BSE-infected beef is believed to be the cause of a similar condition in humans, Creutzfeldt-Jakob disease. In this experiment, students examine simulated PCR products from several feed mills, to determine any possible violations of the ban on including animal parts in cattle feed.

Description: In this PCR experiment, students make billions of copies of a small amount of DNA in only 90 minutes. They just need to mix template DNA and primers with PCR beads that contain all of the other components required to carry out a PCR reaction. Students see the increasing amounts of DNA for themselves, taking samples every few cycles and analysing them on a DNA gel.
