Active Recombinant Cynomolgus FCGR2B protein, His-tagged

• Cat.No.: FCGR2B-215C
• Product Overview: Active Recombinant Cynomolgus FCGR2B protein(Q8SPW3)(Ala46-Pro224) is expressed from HEK293 with His tag at the C-Terminus.

Specification

• Species: Cynomolgus
• Source: HEK293
• Tag: His
• Protein Length: 46-224 aa
• Form: Lyophilized from 0.22μm filtered solution in PBS (pH 7.4).
• Bio-activity: Cynomolgus Fc gamma RIIB, His Tag captured on CM5 Chip via Anti-His Antibody can bind Trastuzumab with an affinity constant of 1.75 μM as determined in SPR assay (Biacore T200).
