Target Details

Target: HIV-1 p24 (Human Immunodeficiency Virus 1 Capsid (HIV-1 p24))

Alternative Name: HIV-1 Gag p24 (HIV-1 p24 Products)

Target Type: Viral Protein

Background: HIV-1 Gag p24 is a capsid protein that constitutes the core of AIDS virus, HIV-1, and is produced by digestion of its precursor, Gag p55, by HIV-1 protease. This protein is indispensable for reproduction of AIDS virus and constitutes an essential element in the virus particle. As this protein is detectable from the early stage of AIDS virus infection, and reflects the amount of virus in the blood, it is used as a marker for observing the patient's condition during and after treatment. This protein was over-expressed as a soluble recombinant protein in E. coli with a plasmid carrying the Gag p24 coding region of HIV-1 virus, subtype B, and highly purified by several steps of chromatography. Its molecular weight is 24 kD, same as that of p24 purified from HIV-1 virus particles.
