Interleukin 15 (IL-15) is an immunomodulatory cytokine that stimulates the proliferation of T-lymphocytes.IL-15 exerts its biological activity primarily on T-cells. It is also essential for the development, survival, and activation of NK cells.Increased IL-15 expression has been associated with rheumatoid arthritis, inflammatory bowel disease, and diseases associated with retroviral HIV and HTLV-I. This Recombinant Mouse IL-15 is supplied as Lyophilized powder with high activity, high purity and low endotoxin. Product Properties Synonyms IL15, Interleukin-15, IL-15, MGC9721 Source E.coli Sequence Asn49-Ser162 Accession P48346 Endotoxin < 1.0 EU/μg by the LAL method. Purity > 95%，determined by SDS-PAGE Biological Activity Measure by its ability to induce CTLL-2 cells proliferation. The ED50 for this effect is 1x 10⁵ IU/mg. Formulation Lyophilized from a 0.22 μm filtered solution of 1×PBS, pH 7.4. Tag 6His Physical Appearance Lyophilized powder Shipping and Storage -25 ~ -15 ° C storage, 1 year expiration date after receipt. After re-dissolving, store at 2 ~8 °C, 7 days expiration date. After re-dissolution, store at -25~-15 °C, 3 months expiration date. Compounding method Centrifuge at 3000 rpm for 5 minutes before uncapping. It is recommended that lyophilized proteins be reconstituted in NO bacterial H2O to a concentration of no less than 100 μg/mL and that the stock solution be incubated at room temperature for at least 20 minutes to ensure adequate re-solubilization. Do not vortex! Vigorous shaking may impair the biological activity of the protein. For long-term storage, it is recommended to add a carrier protein or stabilizer (e.g., 0.1% BSA, 5% HSA, 10% FBS, or 5% alginate), and to dispense the re-solubilized protein solution as needed to avoid repeated freezing and thawing. Cautions 1. For your safety and health, please wear lab coat and disposable gloves. 2. This product is for scientific research purposes only.
