HIV2 infections at present, are predominantly found in west Africa where it is the dominant form of HIV. The env gp36 ectodomain is highly conserved and elicits a type-specific antibody response. Hence, most licensed diagnostic assays incorporate gp36-derived antigens to detect HIV2 specific antibodies. It is becoming important to differentiate between single infection with either HIV1 or HIV2 and dual infection. Alternative Names: HIV1 gp36, Glycoprotein 36 protein, HIV-1 gp36 protein, HIV-1 gp36 protein, HIV 1 gp36 protein, HIV 1 gp36, gp36 protein, SU protein, HIV gp36 Recombinant protein, Envelope surface glycoprotein gp36 protein, HIV-1 gp36, Surface protein protein, HIV 1 gp36 protein, gp36 glycoprotein protein, gp36 protein, Human Immunodeficiency Virus 1 protein
