Antigen in ELISA and Western blots, excellent antigen for detection of HIV seroconvertors with minimal specificity problems.

Recombinant HIV-1 p55 gag is glycosylated with N-linked sugars and produced in insect cells. Recombinant HIV-1 p55 is 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. p55 is a precursor protein, which is processed to p17 (matrix), p24 (capsid), p7 (nucleocapsid), and p6 proteins by the viral protease. It is called 'assemblin' to indicate its role in viral assembly.

Specificity: Immunoreactive with sera of HIV-infected individuals.
