Specification

• Species: Human
• Source: HEK293
• Tag: His
• Protein Length: 1-288 a.a.
• Form: Lyophilized from sterile PBS, pH 7.4. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
• Bio-activity: 1. Immobilized Rituximab at 1 μg/mL can bind Human FcγRI / CD64 recombinant protein, with a linear range of 0.5-4.0 ng/mL. 2. Captured Human FcγRI / CD64 recombinant protein on Anti-His Chip can bind Bevacizumab (IgG1) with an affinity constant of 5.5 nM as determined in an SPR assay (Biacore T200). 3. Captured Human FcγRI / CD64 recombinant protein on Anti-His Chip can bind Nivolumab (IgG4) with an affinity constant of 13.6 nM as determined in an SPR assay (Biacore T200). 4. Loaded Human FcγRI / CD64 recombinant protein on His1K Biosensor, can bind Nivolumab (IgG4) with an affinity constant of 8.5 nM as determined in a BLI assay (ForteBio Octet Red384) . 5. Loaded Human FcγRI / CD64 recombinant protein on His1K Biosensor, can bind Bevacizumab (IgG1) with an affinity constant of 4.7 nM as determined in a BLI assay (ForteBio Octet Red384). 6. Loaded Rituximab (IgG1) on ProA Biosensor, can bind Human FcγRI / CD64 recombinant protein with an affinity constant of 0.38 nM as determined in a BLI assay (ForteBio Octet Red384).
• Molecular Mass: The recombinant human CD64A consists of 284 amino acids and has a predicted molecular mass of 32 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of the recombinant human CD64A is approximately 45-60 kDa due to glycosylation.
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method
• Purity: > 95 % as determined by SDS-PAGE. > 90 % as determined by SEC-HPLC
• Storage: Samples are stable for up to twelve months from date of receipt at -20°C to -80°C. Store it under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted 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.
