• Cat.No.: IL2RB-947H
• Product Overview: Active Recombinant Human IL2RB protein(NP_000869)(Ala27-Asp239) is expressed from HEK293 with His tag at the C-terminus.

Specification

• Species: Human
• Source: HEK293
• Tag: His
• Protein Length: 27-239 aa
• Form: Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4).
• Bio-activity: Human IL-2 R beta, His Tag captured on CM5 Chip via Anti-His Antibody can bind Human IL-2, No Tag with an affinity constant of 0.21 μM as determined in SPR assay (Biacore S200).
• Molecular Mass: The protein has a predicted MW of 26.2 kDa. Due to glycosylation, the protein migrates to 38-50 kDa based on Bis-Tris PAGE result.
