Listed are ELISA Kits for the detection of Activin A, an alias name of SMAD family member 2. The human protein, encoded by the gene SMAD2, is 467 amino acid residues long and has a mass of 52,306 daltons. However, there are up to 2 reported isoforms. It is a member of the Dwarfin/SMAD family. This protein is reported to have a cytoplasmic and nuclear cellular localization. For this target protein, ELISA kits with the following species reactivities are available: human, mouse, rat, bovine, chicken, primate, guinea pig, fish, and other mammalian. This target may also be known as: mothers against decapentaplegic homolog 2, MAD homolog 2, SMAD mothers against DPP homolog 2, Sma- and Mad-related protein 2, JV18, JV18-1, and MADH2.
