| Insulin-Like Growth Factor I, Recombinant, Rat (IGF1) is a well-characterized basic peptide believed to be secreted by the liver and to circulate in the blood. It has growth-regulating, insulin-like, and mitogenic activities. This growth factor has a major, but not absolute, dependence on Somatotropin. It is believed to be mainly active in adults in contrast to Insulin like Growth Factor 2, which is a major fetal growth factor. | | | Catalog # | I7661-09Q | | Biological Activity | Rat IGF-1 is fully biologically active when compared to standards. The ED50, was calculated 2 methods: 1. Stimulation of protein synthesis in rat L6 myoblasts ED50 was found to be 30ng/ml. 2. Type 1 IGF receptor binding assay ED50 was found to be 10ng/ml. | | AA Sequence | The sequence of the first five N-terminal amino acids was determined and was found to be Gly-Pro-Glu-Thr-Leu. N-terminal methionine has been completely removed enzymatically. | | Storage and Stability | Lyophilized powder may be stored at -20°C. Stable for 12 months at -20°C. Reconstitute with sterile ddH2O, aliquot and store at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer. | | Molecular Weight | 7.7kD | | Purity | ~95% Analysis by RP-HPLC; Reducing and non-reducing SDS-PAGE. | | Form | Supplied as a lyophilized powder. Reconstitute with sterile dH2O PBS to 0.1-1mg/ml, which can be further diluted into other aqueous solutions. | | | Important Note | This product as supplied is intended for research use only, not for use in human, therapeutic or diagnostic applications without the expressed written authorization of United States Biological. |
