Serum contains a variety of small molecules, as well as hundreds of different serum proteins. Serum proteins are frequently separated and characterized by electrophoresis in the clinical laboratory to determine the concentration of various proteins and to detect abnormal protein species. In this exercise, students use electrophoresis to study cow serum and to identify major serum proteins including albumin, transferrin and antibodies. This exercise serves as a good introduction to the function and complexity of proteins in blood.
