Cloning and expression of porcine β1,4 N‐acetylgalactosaminyl transferase encoding a new xenoreactive antigen

Abstract excerpt

BACKGROUND: Xenograft rejection of pigs organs with an engineered mutation in the GGTA-1 gene (GTKO) remains a predominantly antibody mediated process which is directed to a variety of non-Gal protein and carbohydrate antigens. We previously used an expression library screening strategy to identify six porcine endothelial cell cDNAs which encode pig antigens that bind to IgG induced after pig-to-primate cardiac...
