801. Serum Proteins and the Western Press-Blot (EXP-801)
Western blotting is one of the most powerful methods in molecular biology for identifying and characterizing specific proteins in complex protein mixtures. We have now streamlined western-blotting procedures so that the entire analysis can be performed during a single 3-hour, or two 2-hour laboratory sessions. In exercise 801, students use the procedure outlined below to identify albumin, transferrin and gamma globulins in serum and then to study the evolutionary relationships of albumin in vertebrates.
