Abstract
This invention discloses novel polypeptides having an antigenic determinant or determinants immunologically cross-reactive with determinants of a glycoprotein having a molecular weight of approximately 41,000 daltons, and determinants of a glycoprotein having a molecular weight of approximately 160,000 daltons which are obtained from cells infected with human immunodeficiency virus-1. The invention further discloses novel polypeptides having an antigenic determinant or determinants specific for a glycoprotein having a molecular weight of approximately 41,000 daltons obtained from cells infected with human immunodeficiency virus-1, the polypeptides further having an antigenic determinant or determinants immunologically cross-reactive with at least one glycoprotein having a molecular weight of 25,000 to 35,000 daltons, 45,000 daltons to 60,000 daltons, 80,000 to 100,000 daltons or 180,000 or 220,000 daltons, which are obtained from HSB, St, HeLa and human cells. The novel polypeptides of the invention are useful in methods of interfering with the effects of HIV-1 upon host cells having cell surface polypeptides capable of binding HIV-1. Methods of assay for HIV-1 infection are also d…
