Purified class I histocompatibility antigens (SLA) from three haplotypes were prepared by papain treatment of lymphoid cell membranes obtained from spleens and lymph nodes of miniature swine homozygous at their major histocompatibility complex. Antigens were purified by ion-exchange chromatography followed by gel filtration. Purity was analyzed by SDS-PAGE, and antigenic specificity by inhibition of complement-dependent, alloantiserum-mediated cytotoxicity. The SLA antigens were reduced and alkylated, and the component heavy and light chains were isolated by gel filtration under dissociating conditions. N-terminal amino acid sequences were obtained for SLAaa, SLAcc, and SLAdd heavy chains, as well as for the light chain, beta 2-microglobulin. The swine antigens showed high levels of homology with class I antigens from other animal species. Heterogeneity was observed among the swine haplotypes, and several of the positions at which substitutions were found are apparently invariant in other animal species. In contrast, only minimal sequence heterogeneity was detected within haplotypes, the basis of which may be of relevance to understanding the evolutionary development of these molecules.
