Recombinant Human KGF1

Recombinant Human KGF1

• Synonyms: HBGF-7
• CAS Number: 9000-83-3
• Source: Escherichia coli.
• Purity: > 96 % by SDS-PAGE and HPLC analyses.
• Bioactivity: Fully biologically active when compared to standard. The ED50 as determined by thymidine uptake assay using FGF-receptors transfected BaF3 cells is less than 10 ng/ml, corresponding to a specific activity of > 1.0 × 105 IU/mg.
• Molecular Weight: Approximately 18.9 kDa, a single, non-glycosylated polypeptide chain containing 163 amino acids.
• Storage Conditions: This lyophilized preparation is stable 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.
• Formulation: Lyophilized from a 0.2 µm filtered solution in 20 mM PB, 0.5 M NaCl, pH 8.0.
• Host or Source: Human
