  • CSC-CTK0199
  • Description
  • Recombinant Human Insulin Like Growth Factor-I (rHu IGF-I) is a polypeptide growth factor, which stimulates the proliferation of a wide range of cell types including muscle, bone, and cartilage tissue. Human IGF-I is a 7.6 kDa protein containing 70 amino acid residues.
  • Species
  • Human
  • Product Overview
  • Human IGF1 expressed in E.coli
  • Molecular Mass
  • 7.6 kDa
  • Size
  • CAT# CSC-CTK0199-100 (100 μg); CAT# CSC-CTK0199-500 (500 μg)
  • Expression System
  • E.coli
  • Purity
  • Greater than 95% as determined by SDS-PAGE and RP-HPLC analysis.
  • Activity
  • The ED50 as determined by the dose-dependent stimulation of thymidine uptake by BALB/c 3T3 cells is ≤ 1.0 ng/ml, corresponding to a specific activity of Greater than 1 x 10^6 units/mg. For most in vitro applications, IGF-I exerts its biological activity in a concentration ranging between 0.2 to 20 ng/ml.
  • Endotoxin Level
  • Less than 1 EU/μg.
  • Formulation
  • Lyophilized from a sterile-filtered protein solution with no additives.
  • Reconstitution
  • Please centrifuge product briefly before opening the vial. The lyophilized protein should be reconstituted in sterile, ultra-pure water to a concentration of 0.1-1.0 mg/ml. This solution can then be diluted into other aqueous buffers and stored at -20°C for future use.
  • Storage & Stability
  • The lyophilized IGF-I, though stable at room temperature for up to 3 weeks, is best stored desiccated at -20°C. Reconstituted IGF-I should be used immediately or stored long-term in undiluted working aliquots at -20°C. For long-term storage, it is recommended to add a carrier protein (0.1% HSA or BSA). Please avoid repeated freeze / thaw cycles.
