Insulin-like growth factor 2 (IGF-2) is one of three protein hormones that share structural similarity to insulin. The major role of IGF-2 is as a growth promoting hormone during gestation. It is believed to be a major fetal growth factor in contrast to Insulin-like growth factor 1, which is a major growth factor in adults.

<0.1 EU per 1 μg of the protein by the LAL method.
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 > 3x 105 IU/mg.
>98% as determined by SDS-PAGE. Ni-NTA chromatography
The protein was lyophilized from a solution containing 1X PBS, pH 8.0.
It is recommended to reconstitute the lyophilized protein in sterile H2O to a concentration not less than 100 μg/mL and incubate the stock solution for at least 20 min to ensure sufficient re-dissolved.
Lyophilized protein should be stored at -20°C. Upon reconstitution, protein aliquots should be stored at -20°C or -80°C.
Please use within two weeks after protein reconstitution.
