The ELISA kits listed below target S100A4, the symbol for the human gene, S100 calcium binding protein A4, and a member of the S-100 family. The protein encoded by S100A4 has a predicted amino acid length of 101 and a mass of 11.7 kDa. S100A4 may also be known by the following names: metastasin 1, malignant transformation suppression 1, fibroblast-specific protein-1, calcium placental protein, and protein S100-A4, and placental calcium-binding protein. Orthologs of the gene, including human, mouse, rat, bovine, and other mammalian are available targets of several ELISA kits.
