Methods and materials for HIV detection

Abstract

Disclosed are immunologically active polypeptides, preferably antibodies or antibody fragments, and most preferably monoclonal antibodies, which are reactive with idiotypes of antibodies to human lymphocyte T4 protein and are reactive with the HIV virion in a manner allowing for in vitro and in vivo neutralization of HIV infectivity and detection of HIV particles in biological fluids. Presently preferred embodiments comprise monoclonal anti-monoclonal-anti-human lymphocyte T4 antibodies produced by new murine hybridoma cell lines JT4C8, JT4C12, JT4C16, JT1-1F3, JT1-1F3-E5, JT1-1D7 and JT2-N15. Also disclosed are active and passive vaccination procedures.
