Disc electrophoresis of turkey serum alkaline phosphatase isoenzymes using polyacrylamide gel. 1. Procedure.

The isoenzymes of alkaline phosphatase in turkey serum were separated by disc electrophoresis using polyacrylamide gel as the supporting medium In this laboratory we have been unable to adapt polyacrylamide gel electrophoresis procedures for turkey serum that had been described by previous workers as successful in separating the isoenzymes of avian alkaline phosphatase. A rapid and repeatable procedure that yielded excellent resolution of alkaline phosphatase isoenzymes was devised. This procedure involved a step-by-step determination of the following: a suitable gel system, buffer system, staining procedure and sample preparation.
