DATA SHEET:recombinant RAT INTERLEUKIN-15

-IL-15 is an immunomodulating cytokine that shares many biological properties of IL-2. They share common receptor subunits, the beta and gamma chains of the IL-2R, resulting in crucial functions in the development, survival and activation of NK and T cells. IL-15 is a co-stimulator for proliferation of PMA or anti-IgM activated purified B cells. Unlike IL-2, IL-15 acts as an agonist of human neutrophils and proliferates mouse mast cells and bone marrow-derived mouse mast cells. Increased expression of IL-15 has been reported in patients with rheumatoid arthritis, inflammatory bowel disease and diseases affiliated with retroviruses HIV and HTLV-I. This recombinant Rat IL-15 is a 13.5 kDa protein, consisting of 115 amino acid residues.

Catalog#: RDI-4024

Package Size:

10 micrograms $231.00   $219.00/package 2 or more

 -Mini-Pack# cat#RDI-4024p $94.00/2ug


Supplied: Lyophilized powder with no additives.

Source: E. Coli

Purity: >96% by SDS-Page and HPLC analysis. Endotoxin level is less than 0.1ng per ug (1EU/ug) of rat IL-15

Reconstitution: At first use, tighten cap, genetly tap on counter or centrifuge 1 minute 1000 rpm to concnetrate powder in bottom of vial. The lyophilized IL-15 should then be reconstituted in 50mM Tris pH8.5 to a concentration of 0.1- 1mg/ml. Allow to set at least 30 minutes at 4 DEG C, Mix well. If desired, centrifuge for 1-2 minutes at 1000 rpm to concentrate material in vial. This solution can be diluted into other buffered solutions or stored at 4 DEG C for 1 week or -20 DEG C for future use.

Note:If this material is not to be used for coating or labeling (or other applications requiring carrier free material), the addition of 0.1% BSA to later dilution buffers or dilution in sterile culture media is recommended to enhance stability and minimize absorption to vial. Ideally, maintain stock >10ug/ml.

Storage: The lyophilized powder is stable at room temperature for a few weeks but it is best stored desiccated at - 20 DEG C. Reconstituted IL-15 should be stored in working aliquots at -20 DEG C. AVOID FREQUENT FREEZE THAW CYCLES.

Reactivity: The ED50 as determined by the stimulation of the proliferation of murine CTLL-2 cells is <10ng/ml corresponding to a specific activity of > 100K units/mg.
