The Plasma Cell Differentiation Antigen PC.1 is Absent in CH3/Tif and Present in C3H/HeJ

Abstract
(C3H/Tif × DBA/2)F1 mice, immunized with viable BALB/c plasmacyloma MOPC315 cells, produce antibodies directed against a cell‐surface antigen. The strain and lissue distribution of this antigen was identical to that of the plasma cell differentiation alloantigen PC.1. The antigen is absent in the mouse strain C3H/Tif but is present in the closely relaled substrain C3H/HeJ. This is the third difference between surface structures of the B‐cell lineage of C3H/Tif and C3H/HeJ mice.
