The ELISA kits listed below target STAT1, the symbol for the human gene, signal transducer and activator of transcription 1, and a member of the Transcription factor STAT family. The protein encoded by STAT1 has a predicted amino acid length of 750, a mass of 87.3 kDa, and a cytoplasmic and nuclear subcellular localization. There are currently 2 reported isoforms. Pathologic involvement is reported in Immunodeficiency 31B. STAT1 may also be known by the following names: IMD31B, IMD31A, transcription factor ISGF-3 components p91/p84, signal transducer and activator of transcription 1 91kDa, signal transducer and activator of transcription 1 91kD, signal transducer activator of transcription 1-alpha/beta, and STAT91. Orthologs of the gene, including human, mouse, rat, chicken, primate, guinea pig, plant, and other mammalian are available targets of several ELISA kits.
