Human IGF-II (Receptor Grade), recombinant protein

Insulin-like Growth Factor-II, human, Synonyms: insulin like growth factor-2, IGF-2, Somatomedin A, ILGF2, T3M-11-derived growth factor,

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.
