Description			Syk is a cytoplasmic 72kD non-receptor tyrosine kinase that is widely expressed in hematopoietic cells. The Syk kinase associates with a number of proteins including c-Src, Lck, Lyn, Fyn, Vav1, STAT3, SHP1, Grb2, and LAT to couple immunoreceptors to downstream signaling events mediating cellular proliferation, differentiation, and phagocytosis. Syk is modified by phosphorylation on multiple tyrosine sites. Source: Recombinant corresponding to aa359-635 from human SYK, fused to GST-tag at N-terminal, expressed in Sf9 cells. Molecular Weight: ~58kD Applications: Suitable for use in the study of enzyme kinetics, screening inhibitors, and selectivity profiling. Other applications not tested. Recommended Dilution: Optimal dilutions to be determined by the researcher. Specific Activity: ~139pmol/min/ug Storage and Stability: Aliquot to avoid repeated freezing and thawing and store at -70°C. Aliquots are stable for 6 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
