Overview
Product name Recombinant Human IL-21 Protein Catalog No. RP02508 Description Recombinant Human IL-21 Protein is produced by Escherichia coli expression system. The target protein is expressed with sequence of Human IL-21 fused with polyhistidine tag at the C-terminus Bio-Activity Measured by its ability to enhance IFN gamma secretion in NK-92 cells. The ED50 for this effect is <10 ng/mL. Purity > 95% by SDS-PAGE. Endotoxin < 0.1 EU/μg of the protein by LAL method. Formulation Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4. Species Human Background
Interleukin-21 (IL21) belongs to the IL-15/IL-21 family. It is a cytokine with immunoregulatory activity. Cytokines are proteinaceous signaling compounds that are major mediators of the immune response. They control many different cellular functions including proliferation, differentiation and cell survival/apoptosis but are also involved in several pathophysiological processes including viral infections and autoimmune diseases. Interleukin-21 is a cytokine that has potent regulatory effects on cells of the immune system, including natural killer (NK) cells and cytotoxic T cells that can destroy virally infected or cancerous cells. This cytokine induces cell division/proliferation in its target cells.Product information
