Abstract
There are provided membrane-associated polypeptides having the sequence shown in SEQ ID Nos. 1 and 9. Also provided are immunogenic determinants derived from said polypeptides and antibodies raised thereto. The polypeptides, their derived antigenic determinants and the antibodies are useful for the diagnosis and treatment of metastatic potential in tumors.
Claims3
A method of detecting cells of metastatic potential comprising the steps of:
- (a) contacting an antibody of accession no. DSM2256 or DSM2257 with a cell or tissue sample, said antibody being capable of specifically recognizing an epitope of a polypeptide comprising an amino acid sequence encoded by a nucleotide sequence according to SEQ ID No:1 or SEQ ID No:8, and
- (b) detecting binding of said antibody to said cell or tissue sample.
An isolated monoclonal antibody obtained from a hybridoma deposited under accession nos. DSM2256 or DSM2257.
A method of identifying cells with metastatic potential comprising the steps of:
- (i) providing an antibody of accession nos. DSM2256 or DSM2257 capable of specifically recognizing an epitope of a cell-membrane associated polypeptide encoded by a nucleic acid sequence according to SEQ ID No:
- 1 or SEQ ID No:
- 8,
- (ii) incubating said antibody with cell of interest, and
- (iii) detecting binding of said antibody to said cells, wherein the antibody binding indicates said cells have metastatic potenial.
