| p24 | <protein> Protein antigen from HIV's core that can be measured in blood and other body fluids. Measurement of p24 levels in the blood have been used to monitor viral activity, although this is not considered a very accurate method due to the existence of p24 antibody that binds with the antigen and makes it undetectable.

| HIV core protein p24 | A major core protein of the human immunodeficiency virus encoded by the HIV gag gene. HIV-seropositive individuals mount a significant immune response to p24 and thus detection of antibodies to p24 is one basis for determining HIV infection by elisa and western blot assays. The protein is also being investigated as a potential HIV immunogen in vaccines. (12 Dec 1998) |
