Provided below are ELISA kits targeting transferrin, a human protein encoded by TF. This protein is 698 amino acids long, with a mass of 77.1 kDa, and is a member of the Transferrin family. This is reported to be a secreted protein. There is a noted implication in Atransferrinemia. Other alias names for this protein include: serotransferrin, beta-1 metal-binding globulin, epididymis secretory sperm binding protein Li 71p, siderophilin, PRO1557, PRO2086, and TFQTL1. ELISA kits are available that are reactive to human, mouse, rat, bovine, chicken, primate, guinea pig, and other mammalian variants of the target antigen.
