Species: Human Expressing host: HEK293 cells Description: Recombinant Human c-Kit/CD117 Protein is produced by HEK293 expression system. The target protein is expressed with sequence (Gln26-Thr520) of human KIT/c-KIT/CD117 (Accession #NP_000213.1) fused with an Fc, 6His tag at the C-terminus. Tag: C-hFc&His Purity: > 97% by SDS-PAGE. Endotoxin: Biological Activity: 1.Measured by its binding ability in a functional ELISA. Immobilized recombinant human SCF at 1 g/mL (100 L/well) can bind recombinant human CD117 with a linear range of 1-6 ng/mL.
2.Measured by its binding ability in a functional ELISA. Immobilized Human SCF at 2 g/mL (100 L/well) can bind c-Kit/CD117 with a linear range of 0.049-9.11 ng/mL. preparation: Lyophilized from a 0.22 m filtered solution of PBS, pH 7.4.Contact us for customized product form or formulation. Storage Store the lyophilized protein at -20C to -80 C for long term.
After reconstitution, the protein solution is stable at -20 C for 3 months, at 2-8 C for up to 1 week.Unopened freeze-dried powder,Store at -20 to -80 °C for twelve months
Redissolution: Centrifuge the vial before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid votex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles.Redissolution:Store at -20 to -80 °C,avoid repeated freeze thaw cycles
Background Information : This protein is human homolog of the proto-oncogene c-kit. C-kit was first identified as the cellular homolog of the feline sarcoma viral oncogene v-kit. This protein is a type 3 transmembrane receptor for MGF (mast cell growth factor, also known as stem cell factor). Mutations in this gene are associated with gastrointestinal stromal tumors, mast cell disease, acute myelogenous lukemia, and piebaldism. Multiple transcript variants encoding different isoforms have been found for this gene. GeneID 3815 Swiss Prot P10721 Alias: KIT;C-Kit;CD117;PBT;SCFR;c-kitMedChemExpress (MCE) recombinant proteins include: cytokines, enzymes, growth factors, hormones, receptors, transcription factors, antibody fragments, etc. They are often essential for supporting cell growth, stimulating cell signaling pathways, triggering or inhibiting cell differentiation; and are useful tools for elucidating protein structure and function, understanding disease onset and progression, and validating pharmaceutical targets. At MedChemExpress (MCE), we strive to provide products with only the highest quality. Protein identity, purity and biological activity are assured by our robust quality control and assurance procedures.
