Active Recombinant Human FCGR2B protein, His-tagged

• Cat.No.: FCGR2B-7279H
• Product Overview: Active Recombinant Human FCGR2B protein(Ala46-Pro217)(P31994-1) was expressed in CHO, with a C-terminal polyhistidine tag.

Specification

• Species: Human
• Source: CHO
• Tag: His
• Protein Length: 46-217 aa
• Form: Lyophilized from sterile PBS, pH 7.4.
• Bio-activity: Measured by its binding ability in a functional ELISA. Immobilized human sCD32b-His (CHO) at 10 μg/ml (100 μl/well) can bind biotinylated human IgG1, The EC50 of biotinylated human IgG1 is 0.18-0.42 μg/ml.
• Molecular Mass: The secreted recombinant human CD32b consists of 183 amino acids and predicts a molecular mass of 20.8 KDa. The apparent molecular mass of the protein is approximately 29 KDa in SDS-PAGE under reducing conditions due to glycosylation.
• Endotoxin: < 1 EU/µg as determined by LAL test.
• Purity: > 97 % as determined by SDS-PAGE
• Storage: Store it under sterile conditions at -20°C to -80°C upon receiving. Recommend to aliquot the protein into smaller quantities for optimal storage. Avoid repeated freeze-thaw cycles.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
