SEC Mobile Phase Screening Service
Sample: | CHO cell expressed Fc Fusion Protein, 160 kD |
Goal: | In search of high resolution separation between protein monomer, dimer, and high molecular weight aggregates. |
Approach: | Screen different mobile phase to achieve best separation and sample recovery. |
Conclusion: | Zenix SEC-300 (3 µm, 300 Å) column delivers baseline separation of Fc fusion protein, its oligomer, and impurity. With the addition of arginine, the hydrophobic interaction between Fc fusion protein and column resin is minimized. |
