Abstract
NUGC4 cells derived from a human gastric cancer gave 6% Hanganutziu-Deicher (HD) antigen-positive cells by flow cytometric analysis using an affinity-purified chicken antibody to N-glycolyneuraminyl-lactosyl-ceramide (HD3 ganglioside). The cells showed no HD antigenic ganglioside by thin-layer chromatography enzyme-immunostaining; however, they were revealed to contain HD antigenic proteins with molecular masses of 150, 100, 90, 70, 65, 60, 47, and 40 kDa, by both immunoblotting after sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and immunoprecipitation of [35S]-methionine-labeled proteins, followed by SDS-PAGE and autoradiography. Neuraminidase treatment destroyed the antigenicity of all proteins, indicating that these molecules are glycoproteins and have N-glycolyneuraminic acid at the non-reducing terminal of carbohydrate chains as an HD antigenic epitope.Entities:
