IL-15 & IL-15RA Protein, Mouse, Recombinant (His) is expressed in HEK293 mammalian cells with His tag. The predicted molecular weight is 34.46 kDa and the accession number is P48346-1 & Q60819-1.

Mouse

HEK293 Cells

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. Predicted N terminal: Asn 49 & Gly 33

A Certificate of Analysis (CoA) containing reconstitution instructions is included with the products. Please refer to the CoA for detailed information.

It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots.

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.
