Background
The IGF2 protein, a member of the insulin-like growth factor family, plays a pivotal role in promoting growth and influencing fetoplacental development, particularly as a major fetal growth hormone in mammals. It is regulated by placental lactogen and contributes to tissue differentiation. In adults, IGF2 is involved in glucose metabolism in adipose tissue, skeletal muscle, and the liver. Acting as a ligand for integrin, it facilitates IGF2 signaling and positively regulates the function of the myogenic transcription factor MYOD1, controlling muscle terminal differentiation. Additionally, IGF2 inhibits myoblast differentiation and modulates metabolism by increasing mitochondrial respiration rates. Moreover, in glucose-mediated co-secretion with insulin, IGF2's counterpart, preptin, acts as a physiological amplifier of glucose-mediated insulin secretion. Notably, IGF2 exhibits osteogenic properties, enhancing osteoblast mitogenic activity through the phosphoactivation of MAPK1 and MAPK3.
Verified Bioactivity
Measure by its ability to induce MCF-7 cells proliferation. The ED50 for this effect is <3 ng/mL. The specific activity of recombinant human IGF-II is >3x105 IU/mg.

Product Properties
Lyophilized powder.
Lyophilized from a 0.22 μm filtered solution of PBS, pH 8.0, trehalose.
<0.1 EU per 1 μg of the protein by the LAL method.
It is recommended to reconstitute to a concentration of 100-200 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).
Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.
Room temperature in continental US; may vary elsewhere.
