The new Qsep400™ system provides quality-controlled assays with specifications developed to measure the purity and heterogeneity of monoclonal IgG antibodies under either reduced or non-reduced states. This capillary zone electrophoresis (CZE) system integrates micro-capillary electrophoretic technology into a plug-and-play disposable pen-shaped multi-capillary gel cartridge with automated liquid handling (96-samples) and real-time fluorescent detection and analysis. Optimized for high resolution and high throughput at ambient temperatures, the Qsep400 provides improved peak resolution, good linear dynamic range, and reproducible migration times with a lowered instrument and sample-analysis cost.
