Product Name: Interleukin-9 Rat Recombinant Synonyms: Interleukin 9, Protein Il9, Il9. Description: Interleukin-9 Rat Recombinant produced in E.coli is a single, non-glycosylated polypeptide chain containing 127 amino acids and having a molecular mass of 14.3kDa.The IL-9 is purified by proprietary chromatographic techniques. Uniprot Accesion Number: D4A8I9 Amino Acid Sequence:MQRCSTSWGI QHTSYLIENL KDDPSSKCSC SANVTSCLCL PIPSDDCTTP CFQEGMSQVT NATQQSKFSP FFFRVKRIVE TLKSNKCQFF SCEKPCNQTT AGNTVSFLKS LLKTFQKTEV QVQRSRA. Source: Escherichia Coli. Physical Appearance and Stability: Lyophilized Interleukin-9 although stable at room temperature for 3 weeks, should be stored desiccated below -18C. Upon reconstitution IL9 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: IL9 protein was lyophilized from a 0.2um filtered concentrated solution in PBS, pH 7.4. 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 Interleukin 9 in sterile 18MO-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions. Biological Activity: The ED50 as determined by a cell proliferation assay using murine TS1 cells is less than 10 ng/ml, corresponding to a specific activity of > 1.0 x 105 IU/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. |
