Recombinant Human FCGR2B protein, His-Avi-tagged, Biotinylated

• Cat.No.: FCGR2B-051H
• Product Overview: Biotinylated Recombinant Human FCGR2B protein(P31994-1)(Ala46-Pro217), fused with C-terminal His and Avi tag, was expressed in HEK293.

Specification

• Species: Human
• Source: HEK293
• Tag: Avi&His
• Protein Length: Ala46-Pro217
• Tag: C-His-Avi
• Conjugation/Label: Biotin
• Form: Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization.
• Bio-activity: Biotinylated Human Fc gamma RIIB, His-Avi Tag captured on CM5 Chip via Anti-his antibody can bind Rituximab with an affinity constant of 5.87 μM as determined in SPR assay (Biacore T200).
• Molecular Mass: The protein has a predicted MW of 22.5 kDa. Due to glycosylation, the protein migrates to 32-37 kDa based on Tris-Bis PAGE result.
• Endotoxin: Less than 1EU per μg by the LAL method.
• Purity: > 95% as determined by Tris-Bis PAGE;> 95% as determined by HPLC
• Storage: Reconstituted protein stable at -80°C for 12 months, 4°C for 1 week. Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
• Reconstitution: Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
