Protein sprouty homolog 4, SPRY4, Sprouty Homolog 4, Spry-4, Protein sprouty homolog 4 isoform 2, Sprouty homolog 4 (Drosophila).
Sprouty Homolog 4 (SPRY4) is an inhibitor of the receptor-transduced mitogen-activated protein kinase (MAPK) signaling pathway. SPRY4 is positioned upstream of RAS activation. SPRY4 protein functions include suppressing the EGFR-transduced MAPK signaling pathway as well as impairing the formation of GTP-Ras.
SPRY4 Human Recombinant produced in E.coli is a single, non-glycosylated polypeptide chain containing 322 amino acids (1-299) and having a molecular mass of 34.9 kDa.
SPRY4 is fused to a 23 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.
Sterile Filtered colorless solution.
The SPRY4 solution (1mg/ml) contains 20mM Tris-HCl buffer (pH 8.0), 10% glycerol and 0.4M Urea.
Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Avoid multiple freeze-thaw cycles.
Greater than 85.0% as determined by SDS-PAGE.
