| Description | Product Specifications Human IGF-II: The Product: Human insulin-like growth factor-II (IGF-II) is a 67amino acid polypeptide that stimulates growth and differentiationin many cell types.Source: IGF-II is synthesized in E. coli using a patented expression system and harvested from the cells as inclusion bodies. The inclusion bodies are dissolved, desalted, the IGF-II is correctly folded under oxidising conditions and then a short leader peptide is cleaved from the peptide product. Several liquid chromatography purification steps are employed to yield receptor grade IGF-II. Link to Sequence:Purity: > 95% (as determined by HPLC and N-terminal sequence analysis)Molecular Weight: 7469 daltons - confirmed by Mass SpectrometryN-terminal sequence analysis of recombinant product: 5 residues >95% single sequenceBiological Activity: (stimulation of protein synthesis in L6 myoblasts) ED50 < 150 ng/mlEndotoxin (LAL): <0.1 EU/ugStability: At least 2 years at 2-4°C(lyophilised)Appearance: White PowderState: Dried from 0.1 M acetic acid: under dry N2 at slightvacuum (-25kPa)Reconstitution: Dissolve in dilute acid (e.g. 10mM HCl or 0.1M acetic acid), aliquot and store at -800C. For lower dilutions (e.g.<1mg/ml) inclusion of a carrier protein is recommended. Avoid freeze-thaw cycles. This is a Gropep specification. ibt is authorized distributor of GroPep. |
