Assignment of gene(s) coding for antigen defined by monoclonal antibody 2B2.
A mouse monoclonal antibody (2B2) recognizes an antigen which is present on most human peripheral blood leukocytes but is absent from most proliferating cells. The antibody precipitated two surface-labeled membrane glycopolypeptides with molecular weights of 86,000 and 145,000, and it was strongly mitogenic to normal human lymphocytes. Somatic cell hybrids have been used for assigning the genes coding for these membrane glycoproteins to human chromosome 21. The assignment was based on correlation of antigen expression on mouse-human T-lymphocyte hybrids with the presence of human chromosomes in the same hybrid clones.
