1,25-Dihydroxycholecalciferol and induction of alkaline phosphatase in organ culture.

Abstract
The report describes investigations which were designed to determine the quantitative relationship between vitamin D3 active metabolites and alkaline phosphatase activity using an organ culture system of embryonic duodenum. The results suggested that alkaline phosphatase could be used as a quantitative index of 1,25 dihydroxycholeciferol in serum and other biological specimens.
