Consistent Performance between AmMag™ Quatro 1300 Automation and Conventional Manual Magnetic Bead Process.

Figure 1. Comparison of purification performance between the AmMag™ Quatro ProAb 1300 Automated System and manual magnetic bead purification. Using 30 mL of CHO cell fermentation broth overexpressing Anti-E2 hIgG (antibody titer 923.3 μg/mL by BLI), samples were purified with 2 mL GenScript Protein A Magnetic Beads (Cat# L00695) via both methods. Analysis of antibody recovery rate, protein purity (SEC-HPLC), and binding activity showed consistent results, with both methods achieving >95% purity and comparable activity to positive controls (PC: protein purification via media; GS-1300: AmMag™ Quatro ProAb 1300; GS-Manual: manual purification).
