Physical Properties of Proteins 8-152

Target Grades: 9-14

This kit demonstrates the important effects of physical parameters such as temperature, pH, salt concentration, and dielectric constants on proteins and illustrates how these effects are used in the isolation and purification of proteins. A protein’s amino acid composition and structure influence its physical characteristics. Experiments include: Isoelectric Precipitation of Casein, Separation of Albumin and Gelatin by Ammonium Sulfate Fractionation, Effects of Acetone on Albumin and Gelatin Solutions, Heat Denaturation of Albumin, and Precipitation of Protein by Lead Acetate. Required, but not included: Bunsen burner, glassware, test tube holders. Contains lead acetate. Designed for 24 students working in six groups of four.
