Human Keratinocye Growth Factor-1 (rHuKGF-1)

• Catalog Number: orb1495034
• Category: Proteins
• Description: Keratinocyte Growth Factor-1 (KGF-1/FGF-7) is one of 23 known members of the FGF family. All FGFs have two conserved cysteine residues and share 30 - 50% sequence identity at the amino acid level. Proteins of this family play a central role during prenatal development and postnatal growth and regeneration of variety of tissues, by promoting cellular proliferation and differentiation. KGF-1/FG-7 is a mitogen factor specific for epithelial cells and keratinocytes and signals through FGFR 2b. KGF-1/FGF-7 plays a role in kidney and lung development, angiogenesis, and wound healing.
• Form/Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.
• MW: Approximately 19.0 kDa, a single, non-glycosylated polypeptide chain containing 164 amino acids.
• Protein Sequence: MCNDMTPEQMATNVNCSSPERHTRSYDYMEGGDIRVRRLFCRTQWYLRIDKRGKVKGTQEMKNNYNIMEIRTVAVGIVAIKGVESEFYLAMNKEGKLYAKKECNEDCNFKELILENHYNTYASAKWTHNGGEMFVALNQK GIPVRGKKTK KEQKTAHFLP MAIT
• Source: Escherichia coli.
• Biological Activity: The biological activity was determined by the does-dependent stimulation of thymidine uptake by BaF3 cells expressing KGF receptors yielding an ED50 < 10ng/ml,corresponding to a specific activity of ≥ 1 x 105 units/mg.
• Endotoxins: Less than 1EU/mg of rHuKGF-1 as determined by LAL method.
• Storage: This lyophilized preparation is stable for several weeks at 2-8°C, but should be kept at -20°C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8°C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20°C to -70°C. Avoid repeated freeze/thaw cycles.
• Buffer/Preservatives: Lyophilized from a 0.2mm filtered solution in 20mM PB, pH 8.0, 1M NaCl.
• Note: For research use only
• Application notes: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at < -20°C. Further dilutions should be made in appropriate buffered solutions.
• Expiration Date: 6 months from date of receipt.
