    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.

    Antigens Involved in Adaptive Immunity

    An antigen is any substance the immune system identifies as foreign and potentially harmful to the body, prompting an immune response. Antigens have two functional properties: immunogenicity and reactivity. Immunogenicity is the ability of an antigen to stimulate a specific immune response. At the same time, reactivity describes the antigen's ability to react with the cells and antibodies produced in response to it.
