Antigens of the transmembrane envelope glycoprotein of a human retrovirus of the HIV-2 type antigens with an immunological relative with them

摘要

The invention relates to an antigenic glycoprotein gp80 characterized by the following properties: it has a molecular weight (PM) close to 80 kDa; it is recognized by polyclonal antibodies directed against the glycoprotein gp300; it includes in association in the form a dimer to entities of the envelope transmembrane glycoprotein gp36, coded by the genome of a human retrovirus of the type HIV-2, susceptible of causing SLA or AIDS in human beings, or any glycoprotein having a molecular weight of the same order of magnitude, capable of forming an immunological complex of the type antigene-antibody, with antibodies directed against said gp80. The invention also relates to antibodies directed against said glycoprotein. It also relates to diagnostic and vaccination applications.
