Placental calcium binding protein in rats. Apparent identity with vitamin D-dependent calcium binding protein from rat intestine.

Abstract

Rat placenta contains a calcium binding protein (CaBP) which is closely related or identical with the vitamin Ddependent CaBP in rat intestine.Placental CaBP was detected using antiserum prepared in rabbits against the intestinal form of the protein purified as previously described (Bruns, M.
