Beschreibung: 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.

Beschreibung: 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.

Beschreibung: Southern blotting is an important technique used widely in clinical genetics and research. By transferring DNA from an agarose gel onto a membrane the method allows the precise analysis and identification of DNA bands on a gel. Using this kit, students use Southern blotting to find a point mutation in the haemoglobin gene indicating Sickle Cell Anaemia.

Beschreibung: 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.

Beschreibung: Bovine spongiforme Enzephalopathie (BSE), auch als Rinderwahnsinn bekannt, ist eine neurodegenerative tödliche Erkrankung von Rindern. Man geht davon aus, dass der Verzehr von Rindfleisch, das mit BSE infiziert ist, beim Menschen zu einer ähnlichen Erkrankung führen kann, der Creutzfeldt-Jakob-Krankheit. In diesem Experiment untersuchen Studenten simulierte PCR-Produkte verschiedener Futtermittelhersteller, um mögliche Verstöße gegen das Verbot von tierischen Bestandteilen im Rinderfutter festzustellen.

Beschreibung: 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.
