Also new are (1) antigens (Ag), forming a single bond in polyacrylamide gel electrophoresis, contg. an epitope recognised by the serum of a carrier of HIV-2 antibodies; (2) immunogens contg. HIV-2 glycoprotein; (3) monoclonal antibdoies (MAb) which specifically recognise (Ag; (4) the hybridomas which produce MAb; and (5) nucleic acid sequences, opt. labelled, derived from at least part of the RNA of HIV-2, or its variants.
