Occurrence of A and B in the Human Body Outside of the Erythrocytes

The antigens A and B are not restricted to the red cells of the blood. They seem to occur in all cells and tissue fluids, except the cerebrospinal fluid, testicle, lens, chorion frondosum of the placenta, hair, compact bone, cartilage,' epithelial cells of the skin, and the nails. This table, taken from Boyd (1) shows the relative amounts in the parts of the body which have been studied quantitatively.
