GMP Human IL-15
Recombinant GMP Human IL-15 is expressed from E.coli without tag.It contains Asn49-Ser162 [Accession | P40933].
The protein has a predicted MW of 12.8 kDa same as Bis-Tris PAGE result.
≥ 95% as determined by SEC-HPLC.
≤ 0.01 EU per μg by the LAL method.
（Residual Host Cell Protein）
（Residual Host Cell DNA）
Lyophilized from 0.22 μm filtered solution in 20 mM Tris, 150 mM NaCl (pH 7.5). Normally 8% trehalose is added as protectant before lyophilization.
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
The product is shipped with ice bag. Store it immediately at -20°C±5°C upon arrival.
-20°C±5°C for 36 months in lyophilized state.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
GMP Human IL-15 on Bis-Tris PAGE under reduced condition.
Measured in a cell proliferation assay using CTLL-2 cells. The ED50 for this effect is 0.1 - 0.3 ng/mL. The specific activity of GMP Human IL-15 is > 1 × 10^7 IU/mg, which is calibrated against the human IL-15 WHO reference standard (NIBSC code: 95/554) (QC Test).
GMP Human IL-15 (reconstituted protein) was stored at 37°C, the protein is stable for 7 days determined by cell based assay.
GMP Human IL-15 (reconstituted protein) was stored at 4°C, the protein is stable for 90 days determined by cell based assay.
GMP Human IL-15 (reconstituted protein) was repeatedly frozen at -80°C and thawed at 37°C, the protein is stable after freezing and thawing 3 cycles determined by cell based assay.

IL-15 belongs to the common gamma chain cytokine family and has pleiotropic immunological functions, and the protein is mainly produced by monocytes, dendritic cells, and epithelial cells. IL-15 plays a crucial role in the development, homeostasis, and function of T, NK and NK-T cells, and is additionally required for various functions of the B cells, dendritic cells (DC), macrophages, and mast cells. Stimulation by IL15 requires interaction of IL15 with components of the IL2 receptor, including IL2RB and probably IL2RG but not IL2RA.
