Anti-serum amyloid A 2 antibodies are used for the immunodetection of the protein encoded by the SAA2 gene. In humans, the canonical protein has a reported length of 122 amino acid residues and a mass of 13.5 kDa. It is known to be a secreted protein. Alternative splicing is reported to yield 2 different isoforms for this protein. It is notably expressed by the liver; secreted in plasma. It is a member of the SAA protein family. Other names for this target antigen include SAA1, serum amyloid A-2 protein, Serum amyloid A-1 protein, and SAA. Gene orthologs have been identified in the mouse and chimpanzee species. Indicated applications for serum amyloid A 2 antibodies listed below include ELISA, Western Blot, Immunocytochemistry, Immunofluorescence, Immunoprecipitation, and Immunohistochemistry.
