Vitamin B12 Content of Cells of the Blood, Bone Marrow and Liver Of the Rat.

Abstract

Summary Vit B₁₂ content was determined microbiologically in different cellular elements of the rat. The highest concentration was found in liver cells. The vitamin B₁₂ content of nucleated bone marrow cells and circulating leukocytes was of the same magnitude, except for the nucleated cells of the skull which had a higher concentration than the other marrow sites. The lowest concentration of vit B₁₂ was found in the red cells.
