Anti-ATP5B antibodies enable researchers to detect and measure the ATP5B antigen in biological samples. This target is a reported synonym of the ATP5F1B gene, which encodes ATP synthase F1 subunit beta. This protein is known to function in angiogenesis and the metabolism of lipids, among other biological roles. The human version of ATP5B has a canonical amino acid length of 529 residues and a protein mass of 56.6 kilodaltons. It is reported to be localized in the mitochondria of cells and widely expressed in many tissue types. ATP5B is a member of the ATPase alpha/beta chains protein family. Over 120 citations in the literature describe the use of ATP5B antibodies in research. Western Blot is a widely used application for these antibodies. ELISA, Immunocytochemistry, Immunofluorescence, and Immunohistochemistry are also common applications.
