Background: Interleukin-21 is a protein that in humans is encoded by the IL21 gene. 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. By radiation hybrid analysis, the IL21 gene is mapped to chromosome 4q26-q27, near the IL2 gene. IL21 stimulates B-cell proliferation in an anti-CD40-dependent manner but inhibits proliferation stimulated by IL4 plus anti-IgM. The biologic effects of IL21 on NK cells differ between species, with human IL21 enhancing NK cell proliferation and murine IL21 inhibiting NK cell proliferation. IL21 is a cytokine highly expressed by mouse T(H)17 cells.

Gene Name: IL21

Production: Natural and recombinant mouse IL-21. There is no detectable cross-reactivity with other relevant proteins.

Standard: Expression system for standard: E.coli, Immunogen sequence: P25-S146

Application Details

Application Notes:

Application Note: Useful in Sandwich ELISA for Quantitative Detection of Antigen. Aliquot 0.1 mL per well of the 4000pg/mL, 2000pg/mL, 1000pg/mL, 500pg/mL, 250pg/mL, 125pg/mL, 62.5pg/mL mouse IL-21 standard solutions into the precoated 96-well plate. Add 0.1 mL of the sample diluent buffer into the control well (Zero well). Add 0.1 mL of each properly diluted sample of mouse cell culture supernates or serum to each empty well. It is recommended that each mouse IL-21 standard solution and each sample be measured in duplicate.
