IL-15 and IL-15 receptor alpha (IL-15Rα) play a significant role in multiple aspects of T cell biology. Interleukin (IL)-15 is essential for natural killer (NK), NKT and memory (m) CD8+ T cell development and function, and is currently under investigation as an immunotherapeutic agent for the treatment of cancer. Recently, the creation of IL-15 superagonist by complexing IL-15 and its high affinity receptor alpha (IL-15 Rα) in solution, inspired by the natural trans-presentation of IL-15, advances the potential of IL-15-based tumor immunotherapy. Gene therapy using engineered cells co-expressing IL-15/IL-15 Rα complex for cancer treatment is also emerging.

Species | Mouse |
Expression System | HEK293 |
Tag | His |
Accession Number | P48346-1 & Q60819-1 |
Construction | A DNA sequence encoding the mouse IL15 (P48346-1)(Met1-Ser162) was expressed with a polyhistidine tag at the C-terminus, constructed the plasmid 1; A DNA sequence encoding the mouse IL15RA (Q60819-1) (Met1-Lys205) was expressed with a polyhistidine tag at the C-terminus, constructed the plasmid 2. The two plasmids were co-expressed and the IL15 & IL15RA heterodimer was purified. |
Protein Purity | > 95 % as determined by SDS-PAGE. > 95 % as determined by SEC-HPLC. |
Molecular Weight | 34.46 kDa (predicted) |
Endotoxin | < 1.0 EU per μg protein as determined by the LAL method. |
Formulation | Lyophilized from sterile PBS, pH 7.4. Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0. 01% Tween 80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hard copy of CoA. |
Reconstitution | A hardcopy of datasheet with reconstitution instructions is sent along with the products. Please refer to it for detailed information. |
Stability & Storage |
Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃. Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles. |
Shipping |
In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise. |
