Product Name: Insulin-Like Growth Factor-2 Human Recombinant Synonyms: Somatomedin-A, IGF2, INSIGF, pp9974, C11orf43, FLJ22066, FLJ44734. Description: Insulin-Like Growth Factor-II Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 67 amino acids and having a molecular mass of 7505 Dalton. IGF-II is purified by proprietary chromatographic techniques. Uniprot Accesion Number: P01344 Amino Acid Sequence:AYRPSETLCG GELVDTLQFV CGDRGFYFSR PASRVSRRSR GIVEECCFRS CDLALLETYC ATPAKSE. Source: Escherichia Coli. Physical Appearance and Stability: Lyophilized IGF-2 although stable at room temperature for 3 weeks, should be stored desiccated below -18C. Upon reconstitution IGFII should be stored at 4C between 2-7 days and for future use below -18C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles. Formulation and Purity: The protein was lyophilized with no additives. Greater than 97.0% as determined by(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE. Application: Solubility: It is recommended to reconstitute the lyophilized IGF2 in sterile 18MO-cm H2O at a concentration of 100ug/ml, which can then be further diluted to other aqueous solutions. Biological Activity: The ED50, calculated by the dose-dependent induction of MCF-7 cell proliferation was found to be 0.85ng/ml corresponding to a Specific Activity of 1, 176, 470IU/mg. Shipping Format and Condition: Lyophilized powder at room temperature. Usage Statement: Our products are furnished for LABORATORY RESEARCH USE ONLY. The product may not be used as drugs, agricultural or pesticidal products, food additives or household chemicals. |
