|Recombinant Human STAT4 Protein is expressed from Baculovirus-Insect Cells with His tag at the N-terminus.It contains Met1-Glu748.
|Signal transducer and activator of transcription 4 (STAT4) is a member of the STAT family and localizes to the cytoplasm. STAT4 is phosphorylated after a variety of cytokines bind to the membrane, and then dimerized STAT4 translocates to the nucleus to regulate gene expression.
|The protein has a predicted MW of 87.75 kDa same as Tris-Bis PAGE result.
|> 95% as determined by Tris-Bis PAGE;> 90% as determined by HPLC
|Less than 1EU per ug by the LAL method.
|Shipped with dry ice.
|Supplied as 0.22 um filtered solution in 20mM Tris, 500mM NaCl, 20% glycerol, 0.5mM DTT (pH 7.5).
|Stability And Storage
|Valid for 12 months from date of receipt when stored at -80°C.； Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
