Anti-B5R antibodies enable researchers to detect and measure the B5R antigen in biological samples. This target is a reported synonym of the CYB5R3 gene, which encodes cytochrome b5 reductase 3. This protein is known to function in cholesterol metabolism and homeostasis, among other biological roles. The human version of B5R has a canonical amino acid length of 301 residues and a protein mass of 34.2 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the mitochondria, ER, and cytoplasm of cells and widely expressed in many tissue types. B5R is a member of the Flavoprotein pyridine nucleotide cytochrome reductase protein family. Western Blot is a widely used application for the B5R antibodies listed below. In addition, ELISA is also a common application.
