Active Recombinant Human IL15 protein

• Cat.No.: IL15-25H
• Product Overview: 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 NaCl (pH 7.5).
• 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 recombinant human IL-15 is > 1 × 10^7 units/mg, which is calibrated against the human IL-15 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: ≤ 0.01 EU per μg by the LAL method.
• Purity: ≥ 95% as determined by SEC-HPLC.
• Storage: -20 to -80°C for 12 months as supplied from date of receipt. -80°C for 3 months after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
• Reconstitution: Dissolve the lyophilized protein in distilled water.
