Overview
The SCIEX BioPhase™ 8800 Capillary Electrophoresis System is an engineered platform for high-throughput, regulatory-grade biomolecular characterization using capillary electrophoresis principles. Based on electrokinetic separation in fused-silica capillaries under controlled electric fields, the system delivers orthogonal analytical data critical for biopharmaceutical development—including size-based separation (CE-SDS), charge heterogeneity profiling (cIEF), and glycoform analysis. Its 8-channel parallel architecture enables simultaneous electrophoretic runs without cross-channel interference, significantly reducing cycle time while maintaining method robustness across all channels. Designed for use in QC, process development, and stability studies, the BioPhase 8800 meets the performance expectations of modern biologics laboratories operating under ICH Q5, Q5A(R2), and USP guidelines.
Key Features
- Eight independent capillary channels with synchronized high-voltage power supply and temperature-controlled cartridge housing for consistent migration times and peak resolution.
- Dual-detection capability—switchable UV-Vis absorbance (190–400 nm) and LIF detection modules—enabling seamless transition between CE-SDS (reduced/non-reduced) and cIEF assays without hardware reconfiguration.
- Integrated capillary conditioning, rinsing, and sample injection protocols to minimize carryover and maximize run-to-run reproducibility (RSD <2% for migration time, <3% for peak area).
- Modular detector design compliant with ASTM E2917-22 for optical path length verification and photometric accuracy validation.
- Thermally stabilized capillary cartridge (±0.1 °C) ensuring retention of conformational integrity for thermolabile proteins and viral vectors during electrophoresis.
Sample Compatibility & Compliance
The BioPhase 8800 accepts standard ANSI/SLAS-format 96-well microplates, enabling direct integration with third-party liquid handlers (e.g., Hamilton STAR, Tecan Freedom EVO) and LIMS interfaces. It supports native and denatured protein analysis, plasmid DNA, AAV capsids, mRNA-LNPs, and antibody-drug conjugates (ADCs). All CE-SDS and cIEF methods are developed in alignment with FDA-recommended practices for biologics characterization and support GLP/GMP documentation requirements. The system’s audit trail functionality complies with 21 CFR Part 11 for electronic records and signatures, including user-level access control, method versioning, and immutable raw data archiving.
Software & Data Management
SCIEX OS software provides a validated, workflow-driven interface for method creation, sequence definition, and real-time electropherogram monitoring. Drag-and-drop method builder simplifies assay setup for CE-SDS and cIEF without scripting. Integrated peak integration algorithms apply baseline correction, mobility normalization, and relative quantitation per ICH Q5A(R2) acceptance criteria. Raw data files (.wiff) are stored with embedded metadata (capillary ID, voltage history, buffer lot, operator ID) to satisfy traceability requirements. Export options include CSV, PDF reports, and XML formats compatible with enterprise data systems (e.g., Empower, LabVantage).
Applications
- Monoclonal antibody (mAb) purity and aggregation assessment via reduced and non-reduced CE-SDS.
- Rapid charge variant profiling of biosimilars and novel modalities using multi-capillary cIEF with imaged detection.
- Quantitative analysis of host cell proteins (HCPs) and product-related impurities in upstream and downstream process samples.
- Stability-indicating assays for thermal, pH, and oxidative stress studies—monitoring deamidation, oxidation, and fragmentation over time.
- Characterization of gene therapy products including empty/full AAV capsid ratios and plasmid supercoiled/linear/nicked forms.
FAQ
Is the BioPhase 8800 compliant with 21 CFR Part 11?
Yes—the system includes full electronic signature support, audit trail logging, and role-based permissions as part of its validated SCIEX OS software suite.
Can CE-SDS and cIEF be run on the same instrument without hardware modification?
Yes—dual-detection modules allow rapid switching between UV and LIF detection modes; no capillary or cartridge replacement is required.
What sample throughput can be achieved in a 24-hour period?
With 8-channel parallel operation and typical run times of 25–40 minutes per assay, up to 384 CE-SDS or cIEF analyses can be completed per day using automated plate loading.
Does the system support method transfer from legacy single-capillary CE platforms?
Yes—SCIEX provides method translation tools and application notes for transferring CE-SDS and cIEF methods from older SCIEX P/ACE™ or Beckman PA 800+ systems.
How is calibration and performance qualification managed?
The system includes built-in PQ checks (e.g., mobility standard injection, lamp intensity verification) and supports IQ/OQ protocols aligned with ASTM E2917 and USP .
