Anti-SID6-306 antibodies enable researchers to detect and measure the SID6-306 antigen in biological samples. This target is a reported synonym of the PPA2 gene, which encodes inorganic pyrophosphatase 2. This protein is known to function in metabolic processes, among other biological roles. The human version of SID6-306 has a canonical amino acid length of 334 residues and a protein mass of 37.9 kilodaltons, although 5 isoforms have been identified. It is reported to be localized in the mitochondria of cells and widely expressed in many tissue types. Other names for this target antigen include HSPC124, SCFAI, and SCFI.
