Detection of N-glycolylneuraminic acid-containing glycoproteins from various animal erythrocytes by chicken monoclonal antibody against Hanganutziu-Deicher antigens.
Two chicken monoclonal antibodies (MAbs), HU/Ch2-7 and HU/Ch6-1, detecting Hanganutziu-Deicher (HD) antigens with N-glycolylneuraminic acid (NeuGc) at a terminal carbohydrate were reactive with bovine, sheep and horse erythrocytes examined by flowcytometry (FCM). The FCM profiles of the three animal erythrocytes treated with trypsin were different from those of non-treated cells and from each other depending on MAbs used. To identify the nature of antigenic molecules, recognized by HU/Ch2-7 and HU/Ch6-1 MAbs, solubilized erythrocytes from the above three animals were analyzed by a Western blotting method. The MAb HU/Ch2-7 identified HD antigen-specific glycoprotein in each of animal erythrocytes. These results indicate that the MAb HU/Ch2-7 is a valuable reagent for the detection of NeuGc-containing gangliosides and glycoproteins.
