SANTA CRUZ BIOTECHNOLOGY, INC.

PSA was determined by sequ- tion range 1:100-1:1000), immunoprecipitation [1–2 µg per 100–500 µg of ence similarity to be a member of the kallikrein subfamily of trypsin prote- total protein (1 ml of cell lysate)], immunofluorescence and immunohisto- ases. PSA is a serine protease that hydrolyzes the major human seminal chemistry (including paraffin-embedded sections) (starting dilution 1:50, protein, the seminal plasma mobility inhibitor precursor, or semenogelin I dilution range 1:50-1:500).
