Biological Activity Comment
- Immobilized Human IL-21, No Tag at 2ug/ml (100ul/well) on the plate. Dose response curve for Human IL-21R, hFc Tag with the EC50 of 42.3ng/ml determined by ELISA.,Human IL-21 on Bis-Tris PAGE under reduced condition. The purity is greater than 95%.,Measured by its ability to enhance IFN-gamma secretion in NK-92 human natural killer lymphoma cells. The ED50-for this effect is <8 ng/mL (QC Test).,The purity of Human IL-21 is greater than 95% as determined by SEC-HPLC.

状态
- Lyophilized
-
溶解方式
- Dissolve the lyophilized protein in 20 mM NaAc, 150 mM NaCl ( pH 5.5). It is recommended to resuspend at 0.5 mg/mL if the lyophilized powder is 100 μg or less, at 1 mg/mL for 500 μg or 1 mg lyophilized powder. Do not mix by vortex or vigorous shaking.
-
缓冲液
- Lyophilized from 0.22μm filtered solution in 20 mM NaAc, 150 mM NaCl ( pH 5.5). Normally 8 % trehalose is added as protectant before lyophilization.

背景
- Interleukin-21 (IL-21), produced predominantly by CD4 T cells and natural killer T (NKT) cells, is a newly discovered member of the common γ-chain family of cytokines. It has been implicated in many immunological processes and has been linked to autoimmune diseases, allergies and other inflammatory diseases.
