Des (1-3) Insulin-like Growth Factor-I, human, recombinant (Receptor Grade) Synonyms: Des(1-3)-IGF-1, Des (1-3) Insulin-like Growth Factor-1

Product Specifications:

Product Code DU

   The Product: Des(1-3) insulin-like growth factor-I, [Des(1-3)IGF-I]
   is a 67 amino acid analog of human IGF-I lacking the N-terminal
   tripeptide Gly-Pro-Glu.  Des(1-3) IGF-I is more potent than IGF-I in
   vitro and in vivo.  This increased potency is due to reduced
   binding of Des(1-3)IGF-I to most of the IGF binding proteins
   produced by cells.  These binding proteins normally inhibit the
   biological actions of IGF-I. The truncated peptide has been found in brain
   and other tissues.

   Source: Des(1-3)IGF-I is produced in E. coli using a
   patented expression system.  Several chromatography purification
   steps are employed to yield the Receptor Grade product.

   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.
