Active Recombinant Human IL2RA, His tagged

• Cat.No.: IL2RA-637H
• Product Overview: Active Recombinant Human IL2RA(P01589)(Glu22-Cys213) is expressed from HEK293 with His tag at the C-terminus.

Specification

• Species: Human
• Source: HEK293
• Tag: His
• Protein Length: 22-213 aa
• Form: Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4).
• Bio-activity: Immobilized Human IL-2 R alpha, His Tag at 1μg/ml (100μl/well) on the plate. Dose response curve for Biotinylated Human IL-2, His-Avi Tag with the EC50 of 93.3ng/ml determined by ELISA.
• Molecular Mass: The protein has a predicted MW of 23.35 kDa. Due to glycosylation, the protein migrates to 40-50 kDa based on Bis-Tris PAGE result.
