Provided below are ELISA kits targeting gelsolin, a human protein encoded by GSN. This protein is 782 amino acids long, with a mass of 85.7 kDa, and is a member of the Villin/gelsolin family. 4 isoforms have been identified. This is reported to be a cytoplasmic and secreted protein. There is a noted implication in Amyloidosis 5. Other alias names for this protein include: actin-depolymerizing factor, brevin, ADF, and AGEL. ELISA kits are available that are reactive to human, mouse, rat, bovine, chicken, primate, guinea pig, plant, and other mammalian variants of the target antigen.
