Recombinant Human IL2RA protein, hFc-tagged

• Cat.No.: IL2RA-636H
• Product Overview: Recombinant Human IL2RA protein(Met 1-Cys 213)(NP_000408.1) precursor was expressed in HEK293 with C-terminal fused human IgG1 Fc region.

Specification

• Species: Human
• Source: HEK293
• Tag: Fc
• Protein Length: 1-213 aa
• Form: Lyophilized from sterile PBS, pH 7.4.
• Bio-activity: 1. Measured by its ability to bind recombinant rat IL2 in a functional ELISA. 2. Measured by its ability to bind recombinant canine IL2 in a functional ELISA. 3. Measured by its ability to bind recombinant mouse IL2 in a functional ELISA.
• Molecular Mass: The mature recombinant human IL2Rα/Fc is a disulfide-linked homodimeric protein generated by proteolytic removal of the signal peptide. The reduced monomer consists of 430 amino acids and has a predicted molecular mass of 48.5 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rhIL2Rα/Fc monomer is approximately 72 kDa due to glycosylation.
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method.
• Purity: > 90 % 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.
