Insulin Like Growth Factor-1 N15 Labeled Human Recombinant ( IGF1 N15 Human )
Data sheet
| Formulation | IGF1 N15 protein was lyophilized from a 0.2um filtered concentrated solution in PBS, pH 7.2. |
| Solubility | It is recommended to reconstitute the lyophilized IGF1 N15 in sterile 18M-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions. |
| Purity | Greater than 97.0% as determined by:(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE. |
| Description | IGF1 N15 Human Recombinant produced in E.coli is a single, non-glycosylated polypeptide chain containing 70 amino acids and having a molecular mass of 7.74kDa.The IGF1 N15 is purified by proprietary chromatographic techniques. |
| Protein Background | 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). |
| Expression host | Escherichia Coli. |
| Synonyms | Somatomedin C, IGF-I, IGFI, IGF1, IGF-IA, Mechano growth factor, MGF. |
| Reagent Appearance | Sterile Filtered White lyophilized (freeze-dried) powder. |
| Stability | Lyophilized IGF1 N15 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IGF1 N15 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. |
| Amino acid sequence | GPETLCGAEL VDALQFVCGD RGFYFNKPTG YGSSSRRAPQ TGIVDECCFR SCDLRRLEMY CAPLKPAKSA. |
| Biological Activity | The ED50 as determined by a cell proliferation assay using serum free human MCF-7 cells is less than 2ng/ml, corresponding to a specific activity of > 5.0 105 IU/mg. |
