Overview

Increase the speed, efficiency, and reliability of charge variant analysis.

All biotherapeutic protein molecules come with charge heterogeneity sites, known as charge variants. Charge variants affect biological functions, such as binding and stability. Charge variant profiles also change dynamically throughout processes, such as sequence expression, chemical degradation, and post-translational modification. It is important to monitor and screen charge variant profiles of biotherapeutic proteins throughout development and manufacturing process.

Revvity’s LabChip® charge variant analysis assays are comparable to traditional CZE assays (Han, 2011) and can resolve and screen the charge variant profile of samples quickly, reliably, and automatically. With the throughput capability on the LabChip® GXII Touch™ protein characterization system, users can optimize their valuable research time to accelerate discovery and development of new biotherapeutic solutions.

Additional product information

Obtain speed and efficiency of charge variant analysis throughout biotherapeutic development and manufacturing processes.

  • Simple and automated operational workflow
  • Fast analysis speed: ~60 seconds per sample
  • High throughput: 96 samples per experiment
  • Minimal sample consumption: 25 μL
  • Full pI range coverage: pI 3 – 9, both acidic and basic proteins
  • Protein migration time can be adjusted based on running buffer pH
  • Good linearity: peak intensity proportional to variant concentration
  • Reliable repeatability with C.V. < 2.5 %

Figure 1. Charge variant profile of a negative charged monoclonal antibody (mAb) on the LabChip low pI charge variant assay. Due to a stronger electrophoretic force, acidic variants move toward the anode faster and arrive earlier at the detection window than main variants and basic variants. Acidic, main and basic variants are separated, resolved and labeled in the LabChip charge variant assay. The relative concentration of each variant was also quantified.

Ordering Information

The Charge Variant Low PI Assay LabChip (CLS153418) is needed to run the assay. It is sold separately.
