Specific immunostaining of CCK cells by use of synthetic fragment antisera

J M Polak et al. Experientia. .

Abstract

Antibodies to the central fragments 9-20 dodecapeptide sequence of CCK were used for specific immunostaining of the CCK cells of the mammalian gut. The use of high specific antibodies to synthetic fragment, essential when there is a possibility of immunochemical cross reactions between antisera and hormones of similar molecular structure provides the key to increased understanding of the nature and relationships of peptide hormones.
