The ELISA kits listed below target STAT4, the symbol for the human gene, signal transducer and activator of transcription 4, and a member of the Transcription factor STAT family. The protein encoded by STAT4 has a predicted amino acid length of 748, a mass of 85.9 kDa, and a cytoplasmic and nuclear subcellular localization. Pathologic involvement is reported in Systemic lupus erythematosus 11. STAT4 may also be known by the following names: SLEB11, and signal transducer and activator of transcription 4 variant 3. Orthologs of the gene, including human, mouse, rat, bovine, chicken, primate, guinea pig, fish, plant, and other mammalian are available targets of several ELISA kits.
