Listed are ELISA Kits for the detection of C(3)G, an alias name of Rap guanine nucleotide exchange factor 1. The human protein, encoded by the gene RAPGEF1, is 1077 amino acid residues long and has a mass of 120,548 daltons. However, there are up to 4 reported isoforms. For this target protein, ELISA kits with the following species reactivities are available: human, mouse, rat, chicken, primate, guinea pig, and other mammalian. This target may also be known as: CRK SH3-binding GNRP, Rap guanine nucleotide exchange factor (GEF) 1, guanine nucleotide-releasing factor 2 (specific for crk proto-oncogene), and C3G.
