Bioactivity

Measured by its ability to enhance IFN-gamma secretion in NK-92 human natural killer lymphoma cells. The ED50 for this effect is ≤ 20 ng/mL. The bioactivity of recombinant Human IL-21(Cat. No. BIC-8414E) is higher than the other competing product.

Quality Data

Recombinant Human IL-21 (Cat. No. BIC-8414E) was analyzed by SDS-PAGE.

Recommended applications depend on the target, product format, and product-specific validation data. Refer to the product datasheet or Certificate of Analysis (CoA), or contact BioCrest Sci for application guidance.
