The STAT proteins (signal transducer and activator of transcription) comprise a family of transcription factors. STATs are activated through tyrosine phosphorylation, mainly by JAK kinases, which results in their dimerization, nuclear translocation and regulation of gene expression. STAT5 activity is induced by numerous cytokines and growth factors. While STAT5A and STAT5B share 96% aa homology, the two isoforms have distinct physiological functions. Phosphorylation of tyrosine 694/699 is a key marker of STAT5A/B activation. Applications: Suitable for use in ELISA, Western Blot and Immunohistochemistry. Other applications not tested. Recommended Dilution: ELISA: 1:25,000 Western Blot: 1:500-1:2000 Immunohistochemistry (Formalin fixed paraffin embedded): 20-40ug/ml Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4 degrees C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. Aliquots are stable for at least 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
