Mouse Anti HIV-I p24 (Clone 4)

HIV-1 Gag p24 antigen is a capsid protein that constitutes the core of HIV-I. p24 protein is detectable starting from the early stage of AIDS virus infection, for this reason it is an interesting marker for disease progression in infected patients. Monoclonal anti p24 antibody clone 4 is designed for the detection of p24 core antigen in human serum or plasma from infected individuals as well as in cell culture supernatant.

Description

Testing of blood donor samples for HIV-1 antigens (p24) was implemented in the United States in 1996 in addition to HIV antibody testing. This decision was based on studies showing that HIV-1 antigen appears in blood early in the course of infection, approximately 1 week before antibody is detectable. Transmission of HIV has been reported from transfusion of seronegative blood that was later shown to contain p24 antigen; the donors subsequently showed seroconversion. Mathematical models, constructed with findings from geographic areas with very high incidence of new HIV infections, suggested that routine antigen testing would detect 1 antigen-positive/antibody-negative donation in every 1.6 million tested. In reality, this projection was not achieved. Only seven donations from infected window-phase (p24 antigen-positive/anti-HIV-negative) volunteer donors were intercepted on the basis of p24 antigen testing alone in the first 5 years of screening, for an observed yield of 1 in 10 million donations. A possible explanation for the underperformance of HIV-1 antigen testing in detecting HIV-1 antibody-negative window period infections is that prospective blood donors in the early phase of HIV-1 infection who have HIV-1 antigen only may be experiencing symptoms from acute retroviral infection that deter them from blood donation or result in their rejection during the predonation history and physical examination.
