• Cat.No.: FCGR2B-1439R
• Product Overview: Recombinant Rat FCGR2B protein(His32-Pro212), fused with His tag, was expressed in HEK293.

Specification

• Source: HEK293
• Species: Rat
• Tag: His
• Form: Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.
• Bio-activity: GMP Monoclonal Anti-Human CD3 Antibody (OKT3) immobilized on CM5 Chip can bind Rat CD32b Protein, His Tag with an affinity constant of 1.93 μM as determined in a SPR assay (Biacore 8K).
• Molecular Mass: This protein carries a polyhistidine tag at the C-terminusThe protein has a calculated MW of 22.4 kDa. The protein migrates as 33-45 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

• Endotoxin: Less than 1.0 EU per μg by the LAL method.
• Purity: >95% as determined by SDS-PAGE. >90% as determined by SEC-MALS.
• Storage: For long term, the product should be stored at lyophilized state at -20°C or lower.Please avoid repeated freeze-thaw cycles. This product is stable after at:
  -20°C to -70°C for 12 months in lyophilized state; -70°C for 3 months under sterile conditions after reconstitution.
• 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.
