HIV p24 ELISA kits are available from several suppliers for investigations on infectious disease. The HIV p24 antigen is the protein that forms the virus's capsid. Also known as capsid protein, p24 folds into a two-domains structure that self-associates to form a ring of five to six members. Due to the initial burst of viral replication upon acute infection, circulating HIV p24 can be detected in the blood prior to the appearance of HIV antibodies. ELISA kits for the detection of HIV p24 antigens or antibodies generally come prepackaged with pre-coated strips or microplates and associated reagents. For more details, visit the supplier page.
