A 46 Kd HUMAN MILK FAT GLOBULE ANTIGEN

摘要

A polypeptide has the antibody binding activity of the 46 Kdalton HMFG antigen and/or homology to at least one of the light chains of clotting factors V and VIII and/or contains RGD and/or EGF-like segments. The polypeptide is provided as a recombinant and/or glycosylated and/or fusion protein. An antibody has high affinity for specificity epitopes of the polypeptide of the invention. Polynucleotide segments encode the polypeptide, recombinant and fusion protein of the invention or fragments thereof, and immunoassay kits comprise the antibodies and/or polypeptides of the invention and other components. In vivo, ex vivo, and in vitro methods of therapy, vaccination and diagnosis utilize the polypeptide, fusion protein anti-sense nucleotides, antibodies or and polynucleotides of the invention.
