title: Monoclonal antibody against human glioblastoma multiforme (U-87MG) immunoprecipitates a protein of molecular mass 38 kDa and inhibits tumor growth in nude mice.
abstract: A monoclonal antibody 6DS1 against a human glioblastoma multiforme cell line U-87MG recognizes a tumor-specific, cell surface antigen of human glioblastoma cell lines. Partial cross-reactivity is observed with two human neuroblastoma cell lines, SK-N-SH and SK-N-MC, with little or no reactivity towards a rat glioma cell line C6 or normal human adult and fetal brain tissues. The antibody recognizes an antigen of molecular mass 38 kDa as inferred from Western blot analysis and sodium dodecyl sulfate-polyacrylamide gel electrophoresis of the immunoprecipitate. The monoclonal antibody 6DS1 inhibits both the attachment to substratum and growth of U-87MG cells. It strongly cross-reacts with xenotransplants of U-87MG cells and inhibits tumorigenesis (subcutaneous implants of U-87MG cells) in nude mice.
