The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
The ED50 was determined by its ability to inhibit IGF-II induced proliferation of MCF-7. The expected ED50 for this effect is ≤ 0.2 µg/ml in presence of 15 ng/ml of human IGF-II.

IGF-binding proteins prolong the half-life of the IGFs and have been shown to either inhibit or stimulate the growth promoting effects of the IGFs on cell culture. They alter the interaction of IGFs with their cell surface receptors.
