Serologically defined specificities of the pig main histocompatibility complex (SL-A)

Abstract
Six antigens detectable by the complement-dependent lymphocytotoxic technique were determined in pigs by 6 groups of alloimmune sera. These specificities are controlled by the main histocompatibility region (SL-A). Serological and genetic studies showed that the given specificities (provisionally designated L1 to L6) form at least 6 haplotypes. Family studies confirmed the linkage between SL-A region and C blood group locus. Maximum lod score values are in recombination fraction .theta. = 0.2.
