Protein; Sino Biological; IL21R Recombinant Human Protein, His Tag; 5 x 5ug; Source: Human; Purity: greater than or equal to 90% by SDS-PAGEInterleukin 21 receptor (IL21R), recombinant human protein is supplied as a lyophilized powder. It is suitable for use in analysis of protein structure. In general, recombinant proteins can also be used as an immunogen, as a protein standard, or in cell biology research applications.
- Activity: 1. Measured by its ability to bind human IL21 in a functional ELISA; 2. Measured by its ability to inhibit IL21-induced Interferon gamma secretion by human natural killer lymphoma NK-92 cells, the ED50 for this effect is typically 1-5ng/mL in the presence of 100ng/mLof recombinant human IL21; 3. Measured by its ability to inhibit IL21 induced Interferon gamma secretion by human natural killer lymphoma NK-92 cells, the ED50 for this effect is typically 50-200pg/mL in the presence of 10ng/mL of recombinant human IL21
- Formulation: Lyophilized in PBS, pH 7.4, 5% Mannitol, 5% Trehalose, and 0.02% Tween 80
- Reconstitution: Dissolve the protein in sterile double distilled water to a concentration of 0.2mg/mL or lower; aliquot and use as soon as possible
