Introduction to Physical Properties of Proteins Lab Activity

Provide a Thorough Overview of the Function of Proteins

Students will discover how physical parameters, such as temperature, pH, salt concentration and dielectric constants affect the isolation and purification of proteins. They will conduct experiments in which they will precipitate casein out of milk, separate albumin and gelatin through fractionation, determine the effects of acetone on albumin and gelatin, denature albumin, and precipitate protein with lead acetate. It includes enough materials for eight setups, a teacher’s guide, and student data sheets.
