Synthetic antigens as immunogens: Part I. The combining site specificities of antibodies formed in rabbits to synthetic disaccharide alpha-L-Fuc-(1----3)-D-Gal.
Antibody to chemically synthesized Fuc alpha 1----3 Gal-1----OC6H4N = N bovine serum albumin was developed. Specificity analysis using related synthetic saccharides was performed. The antisera were shown to be specific for both sugars in the disaccharide, to the 1----3 positional linkage and to the alpha anomeric configuration. Immunohistochemical staining was performed on benign disease and adenocarcinoma tissue of the colon. 5/8 of the benign colon polyp tissue and 4/6 of the colonic adenocarcinoma tissue showed strong granular cytoplasmic staining of the epithelia cells lining the ducts. None of the six normal colon tissues tested showed any reactivity. Immunohistochemical staining was also performed on tissue from benign disease and from carcinoma of the mammary gland. 2/5 of the tissue from benign disease of the breast and 3/6 of the tissue from breast carcinoma showed strong granular cytoplasmic staining of the ductal epithelial cells.
