The protein contains the full-length sequence of HIV-2 coat protein gp32. The protein was purified by proprietary chromatographic technique.
Background: HIV belongs to the retrovirus family, distinguished by possession of a viral reverse transcriptase that transcribes viral RNA into DNA which is integrated into the host-cell genome. Like all retroviruses, HIV-2 encodes gag (nucleocapsid), pol (polymerase), and env (envelope) genes. The env gene, which demonstrates considerable variation from isolate to isolate encodes the gp160/140 precursor of the gp120 outer membrane glycoprotein and the gp32-40 transmembrane glycoprotein.
Specificity: Immuno reactive with all sera of HIV-I infected individuals.
