P24 capsid protein

p24 is a component of the HIV particle capsid. There are approximately 2000 molecules per virus particle, or at a molecule weight of 24 kDa, about 10⁴ virus particles per picogram of p24. The onset of symptoms of AIDS correlates with a reduction in the number of CD4 T cells to less than 450 μL and increased levels of virus and protein p24 in the blood.^[1]
