Description
Source : Escherichia Coli. Insulin-Like Growth Factor-I Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 70 amino acids and having a molecular mass of 7.6kDa.IGF-I is purified by proprietary chromatographic techniques. 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) .
Product Name Alternative
Somatomedin C||IGF-I||IGFI||IGF1||IGF-IA||Mechano growth factor||MGF.
Purification
Greater than 98.0% as determined by: (a) Analysis by RP-HPLC (b) Analysis by SDS-PAGE.
Components
The protein was lyophilized from a 0.2μm filtered concentrated solution in 20mM PB, pH 7.0, 130mM NaCl.
Storage Conditions
Lyophilized Insulin-Like Growth Factor-1 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IGF1 should be stored at 4°C between 2-7 days and for future use below -18°C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA) .Please prevent freeze-thaw cycles.
Applications Notes
It is recommended to reconstitute the lyophilized IGF-1 in sterile 18MΩ-cm H2O not less than 100μg/ml, which can then be further diluted to other aqueous solutions. The ED50 as determined by a cell proliferation assay using murine BALB/C 3T3 cells is less than 1.0 ng/ml, corresponding to a specific activity of > 1ƒâ€”106 units/mg.
