I was doing a search for a related chem and came accross this:
Product Specific Information
This product contains 100 ug of human insulin-like growth factor I (rHuIGF-I).
It is recommended to reconstitute the lyophilized rHuIGF-I in sterile dd H2O not less than 100 ug/ml, which can then be further diluted to other aqueous solutions.
The purity is greater than 98.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Anion-exchange FPLC.
(c) Analysis by reducing and non-reducing SDS-PAGE Silver Stained gel.
The rHuIGF-I is fully biologically active when compared to standards. The ED50, calculated by the dose-dependant proliferation of murine BALB\C 3T3 cells (measured by 3H-thymidine uptake) is < 1.0 ng/ml, corresponding to a specific activity of 1x106 U/mg. For most in-vitro applications, IGF-I exerts its biological activity in the concentration range of 0.2-20 ng/ml.
QUESTION: What would 100 ug of human insulin-like growth factor I (rHuIGF-I) usually go for??
This product contains 50 ug of human fibroblast growth factor-acidic (rHuFGF-a).
