• Source: E. coli
• Biological Activity: Assay #1: Measured by its ability to induce STAT3 signaling in U937 Stat3-Luc reporter cells. Assay #2: Determined by its ability to stimulate the proliferation of human ANBL-6 cells. The expected ED50 is ≤ 1.0 ng/ml, corresponding to a specific activity of ≥ 1 x 106 units/mg
• NCBI: NP_068554.1
• Storage: The lyophilized IL-21 recombinant protein is stable for at least 2 years from date of receipt at -20°C. Reconstituted IL-21 is stable for at least 3 months when stored in working aliquots with a carrier protein at -20°C. As with any protein, exposing IL-21 recombinant protein to repeated freeze / thaw cycles is not recommended. When working with proteins care should be taken to keep recombinant protein at a cool and stable temperature.
• Alternative names: IL-21, Interleukin-21, IL-21
• Note: For research use only
• Expiration Date: 6 months from date of receipt.
