Intrinsic Factor Studies I. Paper Electrophoresis of Mixture of Gastric Juice and Radioactive Vitamin B12.

Abstract

Paper electrophoresis of mixtures of radioactive vit. B12 and concentrated human gastric juice demonstrate that the radioactive B12 is bound to a component of gastric juice which is not one of the major protein peaks and moves toward the anode. This behavior of the vit. B12 was not noted when it was mixed with saline or serum.
