Sony CGX10 Fully Enclosed Flow Cytometric Cell Sorter

Overview

The Sony CGX10 Fully Enclosed Flow Cytometric Cell Sorter is an engineered solution designed specifically for Good Manufacturing Practice (GMP)-compliant cell therapy manufacturing environments. Unlike conventional open-fluidic flow cytometers, the CGX10 implements a fully sealed, single-use fluidic path architecture that eliminates operator exposure to sample aerosols and prevents cross-contamination between runs. Its core sorting mechanism relies on high-precision electrostatic droplet deflection—operating under laminar sheath flow conditions—to achieve high-purity, multi-parameter cell isolation with minimal mechanical or electrical stress on target populations. The system is validated for use in clinical-grade cell processing workflows, including CAR-T, TCR-T, NK cell, and dendritic cell manufacturing, where regulatory traceability, sterility assurance, and consistent cell viability (>95% post-sort under standard protocols) are non-negotiable requirements.

Key Features

• Fully enclosed, single-use fluidic cartridge system compliant with ISO 13485 and FDA 21 CFR Part 11 data integrity standards
• Integrated temperature-controlled sample chamber and collection environment (4–25 °C adjustable, ±0.5 °C stability)
• Up to 10-color excitation/emission detection using solid-state lasers (405 nm, 488 nm, 561 nm, 640 nm) and high-sensitivity GaAsP photomultiplier tubes
• Real-time sort logic engine supporting Boolean gating, hierarchical population nesting, and live compensation matrix application
• Automated alignment and calibration routines with embedded QC metrics (e.g., CV of bead coefficient of variation <3% for FITC/PE/PerCP)
• Onboard sterilization protocol (70% ethanol flush + UV-C irradiation) between cartridges to support multi-shift GMP operations

Sample Compatibility & Compliance

The CGX10 accommodates primary human samples—including peripheral blood mononuclear cells (PBMCs), bone marrow aspirates, leukapheresis products, and enzymatically dissociated tumor digests—within volume ranges of 100 µL to 10 mL per run. All contact surfaces are Class VI USP-compliant, and the disposable cartridge meets ISO 10993 biocompatibility requirements. The platform is aligned with the draft “Annex to GMP – Cell Therapy Products” issued by China’s NMPA, as well as ICH Q5A(R2), ISO 20387:2018 (biobanking), and EU Annex 1 (sterile manufacturing). Full audit trail functionality includes user authentication logs, parameter change history, sort event timestamps, and electronic signatures compliant with ALCOA+ principles.

Software & Data Management

CGX10 operates on Sony’s proprietary CellSort™ Software v3.2, a 21 CFR Part 11–enabled application with role-based access control, electronic signature capture, and immutable data archiving. Raw FCS 3.1/4.1 files, gate definitions, compensation matrices, and sort statistics are automatically archived in encrypted SQLite databases with SHA-256 hash verification. The software supports seamless integration with LIMS via HL7 v2.5 or ASTM E1384 interfaces and provides configurable report templates aligned with FDA eCTD Module 5.3 submission requirements. Batch record generation includes full metadata export (instrument ID, cartridge lot, environmental sensor readings, operator ID, and time-stamped SOP version).

Applications

• GMP-compliant manufacturing of autologous and allogeneic CAR-T cell products (CD3+/CD4+/CD8+/CD25−/CD62L+ subsets)
• Isolation of clinical-grade regulatory T cells (Tregs) for autoimmune disease trials
• Precision enrichment of antigen-specific T cells post-expansion for adoptive immunotherapy
• High-viability sorting of CRISPR-edited hematopoietic stem cells (HSCs) for ex vivo gene therapy
• Multi-modal quality release testing: viability assessment (7-AAD/DAPI), functional marker expression (IFN-γ, Granzyme B), and residual vector detection

FAQ

Is the CGX10 certified for use in commercial-scale GMP manufacturing?
Yes—the CGX10 has completed qualification packages (IQ/OQ/PQ) per ASTM E2500 and is referenced in multiple approved BLA submissions for cell therapy products in the US, EU, and China.
Does the system support integration with closed-process bioreactors or fill-finish lines?
It features standardized 1/8″ Swagelok-compatible ports and Modbus TCP connectivity for programmable handshake with downstream automation platforms such as Sartorius Ambr® or GE FlexFactory™.
Can the CGX10 perform sterile filtration-integrated sorting?
While the sorter itself does not include in-line filtration, its output port is configured for direct connection to sterile, gamma-irradiated tubing sets compatible with 0.22 µm PES membrane filters meeting ASTM F838-22 standards.
What validation documentation is provided with each instrument shipment?
Each unit ships with a Certificate of Conformance, Factory Acceptance Test (FAT) report, and a complete GxP-ready validation toolkit—including blank test protocols, acceptance criteria, and raw data worksheets aligned with PIC/S TR13.
