immunochemically , ba-1 , ba-3 , ba-2 antigenic specificities were studied using the b cell leukemia , knl-14 cells , which was induced in the wka rat with 1-buthy-1-nitrosourea , and it was clarified that as far as ba-1.2 , ba-2.7 , ba-3.3 specificities were concerned , the three antigen specificities were found to be on the different rat ia-like molecules , thus supporting a postulation of the existence of three loci in the rt1-b region , which was suggested by serological analyses .
