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% amino acid homology, the two isoforms have distinct physiological functions. Phosphorylation of tyrosine 694/699 is a key marker of STAT5A/B activation.
Suitable for use in Western Blot. Not suitable for use in Immunoprecipitation. Other applications not tested.
Western Blot: 1:1000-1:2000
Optimal dilutions to be determined by the researcher.
PDGF treated 3T3/NIH cells
Storage and Stability:
May be stored at 4 degrees C for short-term only. For long-term storage, aliquot and store at -20 degrees C. Aliquots are stable for at least 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
