Recombinant Human IL21R protein, His-tagged

• Cat.No.: IL21R-3905H
• Product Overview: Recombinant Human IL21R protein(Q9HBE5-1)(Met 1-Pro 236) was expressed in HEK293, with a polyhistidine tag at the C-terminus.

Specification

• Species: Human
• Source: HEK293
• Tag: His
• Protein Length: 1-236 aa
• Form: Lyophilized from sterile PBS, pH 7.4.
• Bio-activity: 1. Measured by its ability to bind human IL-21 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 1-5 ng/ml in the presence of 10 ng/ml of 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 50-200 pg/mL in the presence of 1 ng/ml of recombinant human IL21.
• Molecular Mass: The recombinant human IL21R consists of 228 amino acids and predictes a molecular mass of 26.5 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rh IL21R is approximately 42-46 kDa due to glycosylation.
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method.
• Purity: > 92 % as determined by SDS-PAGE
• Storage: Store it under sterile conditions at -20°C to -80°C upon receiving. Recommend to aliquot the protein into smaller quantities for optimal storage. Avoid repeated freeze-thaw cycles.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
