Active Recombinant Human Interleukin 15

• Cat.No.: IL15-483H
• Product Overview: Recombinant human IL-15 produced in E.coli is a single, non-glycosylated polypeptide chain containing 114 amino acids and having a molecular mass of 12,773.5 Daltons.

Specification

• Cat. No.: IL15-483H
• Description: Interleukin 15 (IL-15) is a pleiotropic pro-inflammatory cytokine that promotes activation of T cells, neutrophils and macrophages, and is critical to dendritic cell function in several model systems. IL-15 has been shown to play a role in several inflammatory disorders, including rheumatoid arthritis, psoriasis and pulmonary inflammatory diseases. Emerging data suggest that IL-15 may serve as a good therapeutic target as there appears to be a beneficial effect of IL-15 neutralization in models of psoriasis and diabetes.
• Species: Human
• Source: E.coli
• Form: Recombinant IL-15 was lyophilized from a concentrated (1mg/ml) solution with 5mM Tris pH 8.0.
• Purity: Purity Greater than 98% as determined by: Analysis by RP-HPLC. Reducing and non-reducing SDS-PAGE.
• Bio-activity: Recombinant IL-15 is fully biologically active when compared to standards. The ED50, as determined by the dose-dependant stimulation of the proliferation of mouse CTLL-2 cells, was found to be < 0.5 ng/ml.
• Physical Appearance: Sterile Filtered white lyophilized (freeze-dried) powder.
• Solubility: It is recommended to reconstitute the lyophilized product with sterile water at a concentration of 0.1 mg/ml, which can be further diluted into other aqueous solutions.
• Purity Greater than 98% as determined by: Analysis by RP-HPLC. Reducing and non-reducing SDS-PAGE.
• Protein Content determined by: UV spectroscopy at 280 nm. Analysis by RP-HPLC calibrated against a known standard. Quantitation on SDS-PAGE against a known standard.
• Endotoxin Level: Endotoxin level as measured by LAL is <0.01ng/ug or <0.1EU/ug.
• Amino acid sequence: MNWVNVISDL KKIEDLIQSM HIDATLYTES DVHPSCKVTA MKCFLLELQV ISLESGDASI HDTVENLIIL ANNSLSSNGN VTESGCKECE ELEEKNIKEF LQSFVHIVQM FINTS
• Storage: Lyophilized product is very stable at -20 °C. Reconstituted material should be aliquoted and frozen at -20°C. It is recommended that a carrier protein (0.1% HSA or BSA) is added to the sample for long term storage.
• Pathways: Cytokine-cytokine receptor interaction; Jak-STAT signaling pathway
