Purity
Greater than 98% by SDS-PAGE gel and HPLC analyses.Endotoxin level is less than 0.1 ng per μg (1EU/μg) .
Bioactivity
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
Form
Lyophilized
Storage Conditions
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.
