Glycosphingolipid immunostaining: detection of antibody binding with an avidin-biotin enzyme system.
Glycosphingolipids carrying carbohydrate sequences recognized by antibodies and lectins can be detected on thin layer chromatograms using an avidin-biotin enzyme system (ABC reagents). This same method can be used to detect glycosphingolipids blot-transferred from thin layer chromatograms to nitrocellulose. This method has certain advantages over the original radioimmunoassay method, including development of positive bands in minutes after incubation with the substrate, avoidance of handling hazardous radioactive materials and stability of reagents. We have demonstrated the usefulness of this method for immunostaining glycosphingolipids with both monoclonal and polyclonal anti-carbohydrate antibodies. These reagents have previously been used to detect carbohydrate antigens in tissues and isolated cells and now it is possible to use the same reagents for the detection of glycosphingolipid antigens on chromatograms.
