Background: HIV-1 Gag p24

The gag gene of human immunodeficiency virus 1 (HIV-1) encodes a precursor protein known as Pr55Gag. The viral protease PR cleaves this precursor to generate p17, p24, p7, and p6 proteins which are required for virus particle assembly. p24 is a major viral core structural protein. Its measurement is commonly used as an indicator of HIV-1 infection and viral load. This product is intended to be used to generate standard curves and/or positive controls for use in HIV-1 Gag p24 immunoassays.
