AN IMMUNOLOGIC STUDY OF TWO METABOLICALLY ACTIVE PEPTIDES FROM THE ANTERIOR PITUITARY GLAND

Abstract
Peptides I and II, two metabolically active peptides from porcine pituitary glands, stimulated antibody production in rabbits. The antiserum obtained had antibodies which interacted with peptides I and II from porcine pituitaries, peptides I and II from human pituitaries, and fraction H prepared by Rudman from hog pituitaries. None of the other pituitary preparations tested showed any interaction with peptides I and II.
