(separation of Cystine-amino-peptidase and Leucine-amino-peptidase and Their Determination in Pregnant and Nonpregnant Women.)

Serum leucine-aminopeptidase (LAP) and cystine-aminopeptidase (CAP) determinations have been made using a chemical method based on enzymatic hydrolysis of l-leucine-/?-naphthylamide-hydrochloride and cystine-di-/?naphthylamide, respectively. Fractionation of serum proteins by gel filtration on "Sephadex-G 200" has been used for separation of LAP and CAP… (More)
