>95% SDS-PAGE. Purity is greater than 95% by SDS-PAGE gel and HPLC analyses.Endotoxin level is less than 0.1 ng per µg (1EU/µg).
Function
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.
29.7 kDa, under reducing conditions; 25.6 kDa, under non-reducing conditions.
