The ELISA kits listed below target SP1, the symbol for the human gene, Sp1 transcription factor, and a member of the Sp1 C2H2-type zinc-finger protein family. The protein encoded by SP1 has a predicted amino acid length of 785, a mass of 80.7 kDa, and a cytoplasmic and nuclear subcellular localization. There are currently 3 reported isoforms, as well as sites of glycosylation. SP1 may also be known by the following names: specificity protein 1, and transcription factor Sp1. Orthologs of the gene, including human, mouse, rat, and other mammalian are available targets of several ELISA kits.
