These B15 ELISA kits are immunodetection tools for measuring the levels of B15 in biological samples. B15 is an alias of the human NDUFB4 gene, which encodes the protein, NADH:ubiquinone oxidoreductase subunit B4. Notably, B15 is known to play a role in the response to oxidative stress, among other functions. The NDUFB4 protein is 129 amino acid residues in length and 15.2 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is localized to the mitochondria of the cell. Other names for this target antigen include CI-B15.
