Product Specifications Human IGF-I:

Insulin-like growth factor-I (IGF-I) is a 70 amino acid polypeptide that stimulates growth and differentiation in many cell types including rat L6 myoblasts.

Link to Sequence:

Source: IGF-I is produced in E. coli using a patented expression system and the IGF-I is correctly folded and purified by several chromatography steps to yield Receptor Grade IGF-I.

Purity: > 85% (as determined by HPLC and N-terminal sequence analysis)

Molecular Weight: 7649 daltons - confirmed by Mass Spectrometry

N-terminal sequence analysis of recombinant product: 5 residues >95% single sequence

Biological Activity: (stimulation of protein synthesis in rat L6 myoblasts)   ED50  <30 ng/ml

Endotoxin (LAL): <0.1 EU/ugStorage/Stability: At least 2 years at 2-4°C (lyophilised)

Appearance: White Powder

State: Dried from 0.1 M acetic acid: under dry nitrogen at slight vacuum (-25kPa)

Reconstitution: Dissolve in dilute acid (e.g. 10mM HCl or 0.1M acetic acid), aliquot and store at -20°C.  For lower dilutions (e.g. <1mg/ml) inclusion of a carrier protein is recommended.  Avoid freeze-thaw cycles.
