BACKGROUND Natural antibodies that react with galactose-alpha(1,3)galactose [galalpha(1,3)gal] carbohydrate epitopes exist in humans and Old World primates because of the inactivation of the alpha1,3-galactosyltransferase (alpha1,3GT) gene in these species and the subsequent production of antibodies to environmental microbes that express the(More)
Apparently Placenta-specific placental tissue proteins (PP14 and PP17) and solitary tissue proteins (PP16, 19, 20 and PP21) were investigated by avidin-biotin immunoperoxidase technique in the human andcynomolgus monkey placentae, membranes, decidua and umbilical cords. In human early placentae, PP14, 16, 17, 19 and PP21 were localized mainly in the(More)
By means of a thin-layer chromatography immunostaining procedure involving a human monoclonal anti-Lc4Cer antibody, which was estab lished by hybridizing murine myeloma cells and human lymphocytes from a cancer patient, Lc4Cer was proven to be a fetal antigen of human lung and to be a cancer-related antigen in small cell carcinomas of human lung, but not of(More)
