title: DR antigens on melanoma cells: analysis with monoclonal antibodies.
abstract: Two monoclonal antibodies (691-13-17 and 37-7) can precipitate DR antigens from radioiodinated, detergent solubilized melanoma cells. However,  after complete depletion of lysates with one antibody (691-13-17) alpha-like chains can be still be precipitated from some melanoma cells by the other antibody (37-7). Antibody 37-7 also precipitates an additional distinct antigen from SK-MEL 37 but not from any five other melanoma cell lines.
