Active GMP Recombinant Human IL15 protein

• Cat.No.: IL15-4329HG
• Product Overview: GMP Active Recombinant Human IL15 protein(P40933-1)(Asn49-Ser162) is expressed from E.coli without tag.

Specification

• Species: Human
• Source: E.coli
• Tag: Non
• Protein Length: 49-162 aa
• Form: Lyophilized from 0.22 μm filtered solution in 20 mM Tris, 150 mM NACI (pH 7.5). Normally 8% mannitol is added as protectant before lyophilization.
• Bio-activity: 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).
• Molecular Mass: The protein has a predicted MW of 12.8 kDa same as Bis-Tris PAGE result.
• Endotoxin: Less than 0.05 EU per μg by the LAL method.
• Purity: > 95% as determined by Bis-Tris PAGE > 95% as determined by HPLC
• Storage: 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.
• Reconstitution: Dissolve the lyophilized protein in distilled water.
