Proteins and Enzymes

200 ug (also 1 mg)

Lyophilized from a 0.2 µm filtered solution in PBS.

Unconjugated

>97%, by SDS-PAGE with silver staining, under reducing conditions.

Human

7.6 kDa

IGF1

Measured in a serum-free cell proliferation assay using MCF-7 human breast cancer cells. Karey, K.P. et al . (1988) Cancer Research 48 :4083. The ED50 for this effect is 0.3-1.5 ng/mL. The specific activity of recombinant human IGF-I/IGF-1 is 1000 IU/mg, which is calibrated against the human IGF-I/IGF-1 WHO International Standard (NIBSC code: 91/554).

<0.10 EU per 1 µg of the protein by the LAL method.
