Distribution of P 32 in Tissues of Normal Animals. ∗

Abstract

Summary

The distribution and the specific activity of P³² in the various organs of normal animals was studied at 1, 2, and 12 hours after intraperitoneal administration of the isotope. The P³² was rapidly taken up by the serum and distributed in the various organs. It appears that the distribution of P³² was not directly related to the amount of phosphorus present in the tissue but depended on the permeability of the cells to the phosphate ion.
