STAT 5b (Signal Transducer and Activator of Transcription 5b) (FITC)

Store product at 4 degree C if to be used immediately within two weeks. For long-term storage, aliquot to avoid repeated freezing and thawing and store at -20 degree C. Aliquots are stable at -20 degree C for 12 months after receipt. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer.

Reacts specifically with the STAT5b protein and does not exhibit any crossreactivity with the highly related STAT5a protein. Crossreactivity with other endogenous STAT isoforms has not been observed. Specificity was confirmed by Western blot analysis using cell lysates derived from human A431 cells (+/-EGF treatment), NIH 3T3 cells, HeLa cells and MCF-7 cells. Species Crossreactivity: human, mouse and rat.
