    摘要: Dominant negative mutants of mammalian IRS-1 proteins and therapeutic compositions containing such mutants. Also featured are methods of using the dominant negative mutants to inhibit tyrosyl phosphorylation of endogenous IRS-1 in mammalian cells and methods of treating a mammalian malignancy in which tyrosyl phosphorylation of endogenous IRS-1 plays a causative role.

    摘要: A highly sensitive and specific monoclonal-immuno-radiometric assay (M-IRMA) for hCG, using monoclonal antibodies (Mabs) directed against a 37-amino acid synthetic polypeptide analogous to the carboxyl terminus (CTP) of beta-hCG. Accordingly, in one embodiment, a method is described for the determination of human chorionic gonadotrThe present invention was made utilizing funds of the United States Government. The U.S. government is therefore granted a royalty-free, non-exclusive, world wide, paid-up license in this invention.
