Product Specifications

Source:

IGF-II is produced in E.coli using a patented expression system.

Description:

The IGF-II gene encodes a single transcript which results in a 156 amino acid protein, including an 89 amino acid E-domain. Pro-IGF-II is converted to mature IGF-II by sequential cleavage at amino acids 104, 87 and 67. Pro-IGF-II contains sites of O-linked glycosylation. Differential glycosylation and cleavage within the E-domain can therefore result in multiple pro-IGF-II isoforms. The pro-IGF-II proteins make up 10-20% of circulating IGF-II. Pro-IGF-II proteins are secreted by some tumour cell lines and levels are elevated in non-islet cell tumour hypoglycaemia. 

  • Purity: >85 % (as determined by HPLC analysis)
  • Quantity: 20 µg
  • Molecular Weight: The final product contains three major isoforms of pro-IGF-II corresponding to molecular weights of 16.1, 17.0 and 17.6 kDa. These species correspond to the full length 156 amino acid protein and two smaller species corresponding to C-terminal truncations of approximately 5 and 15 residues which result from the purification process
  • N-terminal sequence analysis of recombinant product: 5 residues >95% single sequence
  • Biological Activity: Stimulation of protein synthesis in rat L6 myoblasts (ED50 < 220 ng/ml)
  • Endotoxin (LAL): <0.1 EU/ug
  • Storage/Stability: At least 2 years at 2-4°C (lyophilized)
  • Appearance: White Powder
  • State: Dried from 0.1 M acetic acid under dry nitrogen at a slight vacuum (-25kPa)
