General Notes
Mouse anti Pig CD45 allotypic variant antibody, clone MAC323 recognizes an allotypic determinant of porcine CD45, also known as the leucocyte common antigen (LCA). Mouse anti Pig CD45 allotypic variant antibody, clone MAC323 has been shown to recognize CD45 in pigs of the Large White and German Landrace strains. Another antibody, clone K252.1E4, recognizes a monomorphic determinant on porcine CD45. When K252.1E4 is used in conjunction with MAC323, it can be shown that MAC323 stains a subset of the leukocytes that are detected by K252.1E4; indicating a loss of the epitope in MAC323-ve animals rather than loss of the CD45 antigen. Cross-breeding positive vs. negative animals indicate that the MAC323 gene is inherited in a simple Mendelian autosomal dominant pattern (Binns et al. 1995).
