For in vitro use only!

Shipping: shipped at ambient temperature

Storage Conditions: store at -20 °C
avoid freeze/thaw cycles

Shelf Life: 12 months

Molecular Weight: 13 kDa

Accession number: P48346

Accession number: P48346

Purity: > 95 % (SDS-PAGE, RP-HPLC)

Form: lyophilised (IL-15 was lyophilised from a 1 mg/ml solution with 10 mM Tris-HCL pH 8.0)

Solubility: It is recommended to reconstitute the lyophilised IL-15 in bidest H2O not less than 100 μg/ml, which can then be further diluted to other aqueous solutions. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA)

Activity: ED50: < 5 ng/ml, corresponding to a specific activity 2 x 105 IU/mg, determined by the dosedependent stimulation of the proliferation of CTLL-2 cells.

Interleukin (IL)-15 is a pleiotropic pro-inflammatory cytokine that is expressed in several inflammatory disorders, including rheumatoid arthritis, psoriasis, and pulmonary inflammatory diseases. IL-15 promotes activation of T-cells, neutrophils, and macrophages, and is critical to dendritic cell function in several model systems. Recent emerging data suggest that IL-15 may serve as a useful therapeutic target across a range of disease states. Advances in the past year highlight the beneficial effect of IL-15 neutralisation in models of psoriasis and diabetes. Further evidence for IL-15 expression and effector function has emerged across a range of rheumatic disorders, including juvenile inflammatory arthritis, rheumatoid arthritis, and Kawasaki disease. Interleukin-15 (IL-15) is a gammacommon cytokine, which plays an important role in the development, survival, and proliferation of NK, NK Tand CD8+ T-cells. Recombinant murine IL-15 produced in E. coli is a single, non-glycosylated polypeptide chain containing 115 amino acids and having a molecular mass of 13.3 kDa. IL-15 is purified by proprietary chromatographic techniques.
