Insulin-like Growth Factors (IGF´s), Biotinylated IGF´s and Analogs, Biotinylated Insulin

Des(1-6)IGF-II, recombinant protein (Receptor Grade)

Des(1-6) Insulin-like Growth Factor-II, recombinant Synonyms: Des(1-6)IGF-2, Des(1-6) Insulin-like Growth Factor-2

Produt Specifications Des(1-6)IGF-II:

The Product: Des(1-6) insulin-like growth factor - II [Des(1-6)IGF-II] is a 61 amino acid analog of human IGF-II, lacking the first six N-terminal amino acids. Des(1-6)IGF-II exhibits reduced affinity for IGF binding proteins (IGFBPs), which are known to inhibit the actions of IGF's. Des(1-6)IGF-II has slightly lower affinity for IGFBPs than the IGF-II analog  [Arg6]IGF-II

Source: Des(1-6)IGF-II is produced recombinantly in E. coli using a patented  expression system and chromatography is employed to yield  Receptor Grade  Des(1-6)IGF-II.

Purity: >95% (as determined by HPLC and N-terminal sequence analysis)
