Source: Produced recombinantly in E. coli

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

Molecular weight: 7515 Da, confirmed by Mass Spectrometry

Appearance:Lyophilized white powder

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

Endotoxin (LAL): < 0.01 EU/µg

Biological Activity: Rat IGF-II has a similar potency to human IGF-II for binding to the Type 2 IGF receptors on rat L6 myoblasts. Both ED50 values are approximately 3.8 ng/ml. Rat IGF-II and human IGF-II also exhibit a similar potency for the stimulation of protein synthesis in rat L6 myoblasts. In this assay both ED50 values are approximately 15 ng/ml.

State:Dried from 0.1 M acetic acid and stored under dry nitrogen at a slight vacuum.

Reconstitution:Dissolve in dilute acid (e.g. 10mM HCl or 0.1M acetic acid), aliquot and store at -20°C. For lower dilution (e.g. < 1mg/ml) inclusion of a carrier protein is recommended. Avoid freeze-thaw cycles.
Storage/Stability: At least 2 years at 2-4°C (lyophilized)
