Gibco™ PeproGMP® Human SCF Recombinant Protein, PeproTech®

Description

Recombinant Protein

The human SCF gene encodes for a 273 amino acid transmembrane protein, which contains a 25 amino acid N-terminal signal sequence, a 189 amino acid extracellular domain, a 23 amino acid transmembrane domain, and a 36 amino acid cytoplasmic domain. The secreted soluble form of SCF is generated by proteolytic processing of the membrane anchored precursor. Additional product information and specifications are provided on the Certificate of Analysis. All PeproGMP® products are manufactured using animal-derived component free materials. Product Description/Intended Use: PeproTech GMP recombinant proteins are manufactured for use as ancillary materials by applying applicable principles of GMP and quality control requirements from USP (United States Pharmacopeia) Chapter 1043 Ancillary Materials for Cell, Gene, and Tissue-Engineered Products. Product use statement: For research use or further manufacturing. Not for diagnostic use or direct administration into humans or animals.

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.
