Introduction: The purpose of this experiment is to see the anti-cow antibody bind to cow serum only‚ and we expect to see the anti-cow antibody bind to the spot that had the cow serum. The system we use in this experiment is the serum from Cow‚ Horse‚ Goat‚ Sheep‚ and Donkey‚ Chicken. In order to able to detect and analyze proteins based on their ability to bind to a specific antibody‚ the SDS-PAGE and Western Blot was performed. SDS Polyacrylamide Gel Electrophoresis (SDS-PAGE) is a very common
