Human SCF Protein (PHC2111) in Bioactivity
Immunofluorescence analysis of mast/stem cell growth factor receptor Kit (c-Kit) was performed using HT-29 cells treated with 100 ng/mL of human SCF (c-Kit ligand) recombinant Pprotein (Product # PHC2113) for 30 minutes. Cells labeled with anti-phospho-c-Kit (Tyr703) recombinant polyclonal antibody (22HCLC) (Product # 710762) (Panel a & c; Green). The composite (b & d) represents merged image with DAPI (blue) and F-actin (red) staining. Cells treated with SCF displayed uprgulation of phospho-c-Kit (Tyr703) in comparison with untreated cell...

Reconstitution: Centrifuge the vial briefly, before opening to bring the contents to the bottom. Reconstitute the lyophilized protein in sterile deionized water to 0.1-1.0 mg/mL to regain full activity. Make any further dilutions of the reconstituted protein in low endotoxin medium or buffered solution with FBS or tissue culture grade BSA.
Storage: Store the lyophilized protein at 2-8°C, preferably desiccated. Upon reconstitution, apportion into working aliquots and store at ≤-20°C (not in a frost-free freezer). Avoid repeated freeze-thaw cycles
靶标信息
Stem cell factor (SCF) is the ligand of the c-Kit oncogene and is expressed by various structural and inflammatory cells in the airways. Binding of SCF by the c-Kit receptor leads to homodimerization of the receptor and the activation of signalling pathways such as PI-3, PLC-gamma, Jak/STAT, and MAP kinase pathways. SCF expression leads to the induction of mast cell survival and the expression and release of histamine, pro-inflammatory cytokines and chemokines. The inhibition of the SCF/c-Kit pathway leads to a decrease in histamine levels, mast cell and eosinophil infiltration, IL-4 production and airway hyperresponsiveness, suggesting this pathway may be a useful therapeutic target in inflammatory diseases such as asthma. At least two isoforms of SCF are known to exist.
