purity :
Greater than 98.0% as determined by SDS-PAGE.
form :
The protein was lyophilized with no additives. Sterile Filtered White lyophilized (freeze-dried) powder.
storage stability :
Lyophilized IGF-1 although stable at room temperature for 3 weeks, should be stored desiccated below -18 degree C. Upon reconstitution IGFI should be stored at 4 degree C between 2-7 days and for future use below -18 degree C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles.
other info2 :
Solubility: It is recommended to reconstitute the lyophilized IGF1 in sterile 18M Omega -cm H2O not less than 100 ug/ml, which can then be further diluted to other aqueous solutions. Biological Activity: The ED50, was calculated 2 methods: 1. Stimulation of protein synthesis in rat L6 myoblasts ED50 was found to be < 30ng/ml corresponding to a Specific Activity of 33,334IU/mg. 2. Type 1 IGF receptor binding assay ED50 was found to be <10ng/ml corresponding to a Specific Activity of 100,000IU/mg.

products description :
Description: Insulin-Like Growth Factor I Rat Recombinant produced in E Coli is a single, non-glycosylated, polypeptide chain containing 70 amino acids and having a molecular mass of 7.7kDa. IGF-I is purified by proprietary chromatographic techniques. Introduction: The somatomedins, or insulin-like growth factors (IGFs), comprise a family of peptides that play important roles in mammalian growth and development. IGF1 mediates many of the growth-promoting effects of growth hormone (GH; MIM 139250). Early studies showed that growth hormone did not directly stimulate the incorporation of sulfate into cartilage, but rather acted through a serum factor, termed 'sulfation factor,' which later became known as 'somatomedin' (Daughaday et al., 1972). Three main somatomedins have been characterized: somatomedin C (IGF1), somatomedin A (IGF2; MIM 147470), and somatomedin B (MIM 193190) (Rotwein, 1986; Rosenfeld, 2003).
