Tailin Cell Processing Workstation

Overview

The Tailin Cell Processing Workstation is a fully enclosed, integrated aseptic processing platform engineered for the compliant manufacturing of human cell-based therapeutics under current Good Manufacturing Practice (cGMP) conditions. It operates on the principle of isolator-based containment—leveraging physical separation, unidirectional laminar airflow (ISO Class 5/A), and validated vaporized hydrogen peroxide (VHP®) decontamination to maintain continuous A-grade air quality within the operator work zone. Unlike conventional cleanroom-based workflows, this workstation eliminates dependency on facility-integrated HVAC systems by embedding environmental control directly into the unit’s architecture. It serves as a self-contained alternative to traditional Grade A/B cleanroom suites, supporting end-to-end autologous and allogeneic cell therapy processes—including leukapheresis-derived mononuclear cell isolation, T-cell activation, viral vector transduction, expansion in bioreactor-compatible culture vessels, real-time microscopic monitoring, and final formulation and cryobag filling—all within a single, auditable operational envelope.

Key Features

• Integrated ISO Class 5 (A-grade) laminar airflow system with HEPA-filtered supply air and pressure-controlled differential gradients across internal compartments
• Vaporized hydrogen peroxide (VHP®) decontamination cycle validated per ISO 14644-3 and PDA Technical Report No. 59, achieving ≥6-log reduction of Geobacillus stearothermophilus spores in ≤90 minutes
• Real-time environmental monitoring (temperature, relative humidity, differential pressure, particle count ≥0.5 µm and ≥5.0 µm) with automated data logging compliant with 21 CFR Part 11 requirements
• Embedded high-resolution digital microscopy module with adjustable magnification (up to 400×) and time-lapse imaging capability for live-cell morphology assessment
• Modular mechanical interface design supporting integration of third-party equipment: centrifuges, bioreactors (e.g., Xuri W25, CliniMACS Prodigy-compatible modules), electroporation systems, and automated liquid handlers
• Compact footprint (≤2.8 m² floor space) enabling deployment in existing D-grade or better controlled environments—reducing capital expenditure on cleanroom construction and lifecycle energy costs
• Touchscreen HMI with role-based user access control, electronic batch record (EBR) generation, and audit trail functionality aligned with ALCOA+ data integrity principles

Sample Compatibility & Compliance

The workstation accommodates standard cell culture consumables—including T-flasks, CellSTACKs®, G-Rex bioreactors, cryogenic vials (2–50 mL), and sterile tubing sets—without modification. All wetted materials are USP Class VI-certified and compatible with common cell culture reagents (e.g., FBS, cytokines, lentiviral vectors, electroporation buffers). Regulatory alignment includes full traceability to Chinese GMP Annex for Cell Therapy Products (2023), NMPA Technical Guidelines for Evaluation of Cell-Based Therapies, and international harmonized standards: ISO 13485:2016, ISO 14644-1 (Class 5), PDA TR#13 (Sterile Processing), USP (Ancillary Materials), and EMA Guideline on Quality, Non-Clinical and Clinical Requirements for Investigational Advanced Therapy Medicinal Products. Design qualification (DQ), installation qualification (IQ), operational qualification (OQ), and performance qualification (PQ) documentation packages are provided per ICH Q5A(R2) and Q9 principles.

Software & Data Management

The embedded control software (v3.2+) supports configurable process sequencing, parameter lockout during critical steps, and synchronized timestamped recording of sensor data, operator actions, and HD video streams from up to three internal cameras. All records are stored locally on encrypted SSD storage with optional network backup to secure enterprise servers. Export formats include CSV, PDF-A, and XML for integration with LIMS (e.g., LabWare, STARLIMS) and MES platforms. Electronic signatures comply with FDA 21 CFR Part 11 Subpart B, including biometric authentication options and immutable audit trails covering creation, modification, deletion, and review events—fully auditable during regulatory inspections.

Applications

• Manufacturing of CAR-T, TCR-T, and NK cell therapies under cGMP for clinical trial material (CTM) and commercial production
• Isolation and expansion of mesenchymal stromal cells (MSCs) from bone marrow, adipose tissue, or umbilical cord tissue
• Production of dendritic cell vaccines and tumor-infiltrating lymphocyte (TIL) products
• Process development and scale-down modeling for tech transfer between R&D and commercial facilities
• Training and competency assessment of cell therapy operators in simulated GMP environments

FAQ

Does the workstation support closed-system processing per USP ?
Yes—the entire workflow path from sample entry through final fill is physically isolated using double-door pass-throughs, welded fluid paths, and VHP-sterilized connectors, satisfying closed-system criteria for aseptic processing.
Can it be qualified for use with lentiviral or retroviral vectors?
Yes—integrated VHP decontamination has been validated against enveloped viruses; additional biosafety validation per ISO 14644-5 may be performed onsite with client-supplied challenge agents.
Is remote monitoring and troubleshooting supported?
Yes—secure TLS 1.2-enabled remote access allows authorized engineers to perform diagnostics, firmware updates, and calibration verification without physical presence.
What documentation is included for regulatory submission?
Full GxP-aligned validation master plan (VMP), risk assessment (FMEA), IQ/OQ/PQ protocols and reports, and raw data archives are delivered upon commissioning.
