Provided below are ELISA kits targeting hemoglobin subunit beta, a human protein encoded by HBB. This protein is 147 amino acids long, with a mass of 16 kDa, and is a member of the Globin family. There is a noted implication in Heinz body anemias. Other alias names for this protein include: beta globin chain, hemoglobin beta subunit, hemoglobin beta, CD113t-C, and hemoglobin beta subunit. ELISA kits are available that are reactive to human, rat, primate, guinea pig, and other mammalian variants of the target antigen.
