title: [Monoclonal antibodies to the antigens of human HeLa tumor cells].
abstract: A panel of 6 hybridomas "XEJIMA" producing monoclonal antibodies specific to HeLa cells is prepared. Monoclonal antibodies do not bind to antigens of human diploid fibroblasts, human continuous B- and T-lymphocytes and animal cell lines. The specificity of monoclonal antibodies to cellular antigens of 5 HeLa-like cell lines and 6 human tumour cells lines, not contaminated with HeLa cells, is determined. Antibody containing ascitic fluid and culture media of hybridomas XEJIMA-3, -12, -13, and -22 significantly decrease the attachment of HeLa cells to the surface of culture flasks. Monoclonal antibodies XEJIMA-11, -12 and -13 block the multiplication of HeLa cells. The effect depends on serum concentration in the nutrient medium.
