"Spectrophotometer"

Supplier: EDVOTEK

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

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.
