Anti-APOA antibodies enable researchers to detect and measure the APOA antigen in biological samples. This target is a reported synonym of the LPA gene, which encodes lipoprotein(a). This protein is known to function in the metabolism of lipids and proteolysis, among other biological roles. The human version of APOA has a canonical amino acid length of 2040 residues and a protein mass of 226.5 kilodaltons. It is reported to be notably expressed in the liver. Other names for this target antigen include AK38 and LP. Indicated applications for APOA antibodies listed below include ELISA, Western Blot, and Immunohistochemistry.
