Active Recombinant Human FCGR2B protein, His-Avi-tagged, Low Endotoxin

• Cat.No.: FCGR2B-323H
• Product Overview: Recombinant Human FCGR2B protein(P31994-1)(46-217 aa), fused with C-terminal His and Avi tag, was expressed in HEK293.

Specification

• Species: Human
• Source: HEK293
• Tag: Avi&His
• Protein Length: 46-217 aa
• Form: Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
• Bio-activity: Loaded Human Fc gamma RIIB, His Tag on Anti-His-Biosensor can bind Rituximab with an affinity constant of 3.09 µM as determined in BLI assay.
• Molecular Mass: The protein has a predicted MW of 22.5 kDa. Due to glycosylation, the protein migrates to 28-38 kDa based on Bis-Tris PAGE result.
• Endotoxin: Less than 0.01 EU per μg by the LAL method.
• Purity: > 95% as determined by Bis-Tris PAGE; > 95% as determined by HPLC
• Storage: Store at -20 to -80°C for 12 months as supplied from date of receipt.-80°C for 3 months after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
• Reconstitution: Dissolve the lyophilized protein in distilled water.
