Monoclonal antibody TA99, which specifically binds to a pigmentation associated antigen present on melanoma cells is described. Additionally, the hybridoma cell line deposited with the ATCC under Accession Number HB 8704 from which the antibody is derived, as well as methods for using the antibody are described.

Monoclonal antibody specific for a pigmentation associated antigen

Human monoclonal antibodies (HmAbs) capable of reacting with cytokeratin are disclosed. It has been found that HmAbs De8, M54, M307, Hull, C29, Hu22 and Pa24 may be used to detect these cytoskeletal proteins in various cells. By means of these HmAbs the embryological origin of cells may be determined. This information may be used to determine the possible tissue source of metastasized tumors and greatly affects the management of these cancers.

Human monoclonal antibodies to cytokeratin

Human monoclonal antibodies (HmAbs) capable of reacting with cell surface antigens and intracellular components are disclosed. It has been found that HmAbs Ev248, Ch-5, Ch-13, Te-39, Hu44, Ge-1, Gr-431, Gr169 and Sp909 may be used to detect these antigens in various cells. By means of these HmAbs malignant cells may be determined. This information may be used to screen metastasized tumors and primary tumors for tissue source and greatly affects the management of these cancers.

Human monoclonal antibodies to cell surface antigens

The present invention concerns an autologous precipitating antibody and the gp70 pigment-associated antigen on melanoma cells which it recognizes. The antibody is useful in detecting pigmented melanoma cells in excised specimen, serum or urine.
