The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
% SDS-PAGE. Greater than 95% by SDS-PAGE and HPLC analyses.
This solution can be diluted into other aqueous buffers and stored at 4°C for 1 week or –20°C for future use.
The lyophilized IGF-I is best-stored desiccated below 0°C. Reconstituted IGF-I should be stored at working aliquots at -20°C.

Mechano growth factor
The insulin-like growth factors, isolated from plasma, are structurally and functionally related to insulin but have a much higher growth-promoting activity. May be a physiological regulator of [1-14C]-2-deoxy-D-glucose (2DG) transport and glycogen synthesis in osteoblasts. Stimulates glucose transport in rat bone-derived osteoblastic (PyMS) cells and is effective at much lower concentrations than insulin, not only regarding glycogen and DNA synthesis but also with regard to enhancing glucose uptake.
Involvement in disease
Defects in IGF1 are the cause of insulin-like growth factor I deficiency (IGF1 deficiency) [MIM:608747]. IGF1 deficiency is an autosomal recessive disorder characterized by growth retardation, sensorineural deafness and mental retardation.
