Versatile instrument for protein analysis and quantitation

  • Multiple assays available for quantification, molecular weight sizing, purity, charge variants and glycan analysis. With our pre-verified assays, there is no (or little) method development needed.
  • Rapidly determine the molecular weight, concentration and purity of every protein within your sample
  • Optimal for all throughput needs, with run cherry-picking to 96-well and 384-well high-throughput compatibility
  • Accelerate design space parameters with protein sample analysis from Quality of Design (QbD) and Design and of Experiment (DoE) studies
  • Instrument is applicable throughout the workflow, whether upstream in R&D through Process Development down to final Quality Control.
  • Intuitive touch screen interface with comprehensive analysis using LabChip® GX software enabling “True high-throughput analytics.” Analyze results electropherogram, tabular and virtual gel formats
The platform supports multiple assays for characterizing proteins in reduced and non-reduced samples including:
  • Analyze critical quality attributes in as few as 42 seconds:
  • Titer (concentration and sizing)
  • Purity assessment
  • Aggregation (covalently linked)
  • Stability (degradation / fragmentation analysis)
  • N-Glycan profiling
  • mAb Charge variant / charge heterogeneity
  • mAb impurity analysis (detect minor impurities)
