Anti-HSP90A antibodies enable researchers to detect and measure the HSP90A antigen in biological samples. This target is a reported synonym of the HSP90AA1 gene, which encodes heat shock protein 90 alpha family class A member 1. This protein is known to function in the apoptotic pathway and viral immune response, among other biological roles. The human version of HSP90A has a canonical amino acid length of 732 residues and a protein mass of 84.7 kilodaltons. It is reported to be localized in the cell membrane, nucleus, mitochondria, and cytoplasm of cells and notably expressed in the gallbladder, fallopian tube, epididymis, duodenum, and bronchus. Other names for this target antigen include EL52, HEL-S-65p, and HSP86. A number of HSP90A antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. Immunoprecipitation and Immunohistochemistry are also common applications.
