New monoclonal antibody specific for aurora-A kinase, useful for diagnosis, prognosis and treatment of solid tumors, also for drug screening

摘要

Monoclonal antibody (MAb) that recognizes specifically the human or murine aurora-A kinase (I) binds to membranes that contain (I), can detect and optionally purify (I) by immunoprecipitation, stains biological tissues where (I) is secreted and does not inhibit the enzymatic activity of (I), is new. Independent claims are also included for the following: (1) in vitro diagnosis and prognosis of solid tumors (of breast, stomach or colon-rectum) in humans or animals, using MAb to detect, and optionally quantify, (I) in biological samples; (2) kit for performing method (1), comprising MAb and optionally a marker of cell proliferation, preferably a marker of PCNA, especially an antibody; (3) screening for inhibitors of (I); and (4) preparing MAb.
