Overview
The AgilePulse™ PLUS Bipolar Electroporation System is an advanced, programmable electroporator engineered by BTX (a Harvard Bioscience company) for precision-controlled nucleic acid and macromolecule delivery into mammalian cells—particularly challenging primary and stem cell populations. Unlike conventional monopolar electroporators, the AgilePulse™ PLUS implements true bipolar pulse architecture, enabling independent polarity assignment per pulse group. This capability is grounded in fundamental electrophysiology: alternating electric field direction across successive pulses mitigates asymmetric membrane damage, enhances pore resealing kinetics, and improves post-transfection viability—especially critical in sensitive applications such as CAR-T manufacturing and in vivo gene delivery. The system operates on a modular, scalable platform, supporting both low-volume cuvette-based transfections (e.g., 100 µL–1 mL) and high-throughput, large-scale electroporation (up to 10⁹ cells per run), making it suitable for translational research, process development, and early-stage GMP-aligned workflows.
Key Features
- Five-Group Programmable Pulse Architecture: Each protocol supports up to five independently configurable pulse groups, with individual control over voltage amplitude, pulse duration (0.05–10 ms), inter-pulse interval, number of pulses (1–100 per group), and polarity mode (positive, negative, or polarity reversal).
- Bipolar & Polarity-Reversal Capability: Enables dynamic field inversion during a single protocol—essential for reducing electrode polarization effects, minimizing joule heating, and improving transfection uniformity in adherent and in vivo settings.
- Scalable Electrode Compatibility: Supports standard 0.1–4 mm gap electroporation cuvettes, high-capacity flow-through electrodes (e.g., BTX ECM 830-compatible large-volume chambers), and specialized in vivo applicators (e.g., needle-type and plate electrodes for intramuscular, subcutaneous, or intratumoral delivery).
- Adherent-Cell Transfection Workflow Support: Optimized protocols and electrode configurations allow direct transfection of monolayer cultures without trypsinization—preserving cell morphology, surface receptor integrity, and downstream functional assays.
- Robust Electrical Architecture: Delivers stable high-voltage output (500–1200 V) and low-voltage pulses (100–500 V) with microsecond-level timing resolution and minimal waveform distortion, ensuring reproducibility across replicates and operators.
Sample Compatibility & Compliance
The AgilePulse™ PLUS accommodates a broad spectrum of biological samples: suspension cells (e.g., Jurkat, CHO, PBMCs), adherent lines (HEK293, HeLa, iPSC-derived neurons), primary isolates (human T cells, dendritic cells, hepatocytes), and ex vivo tissue explants. Its design aligns with established electroporation safety and efficacy benchmarks referenced in ISO 13485–aligned quality systems. While the instrument itself is not a medical device, its operational parameters and documentation support compliance with ICH-GCP, USP , and ASTM F2657 (Standard Guide for Electroporation-Mediated Delivery of Macromolecules). When integrated with audit-trail-enabled software platforms, the system meets foundational requirements for 21 CFR Part 11 data integrity in regulated environments.
Software & Data Management
The system operates via BTX’s proprietary AgilePulse Control Software (v3.x+), which provides intuitive graphical protocol building, real-time pulse monitoring, and exportable CSV logs containing timestamped voltage, current, and impedance traces. All protocols are digitally signed and version-controlled; user access levels (administrator, technician, viewer) can be assigned to enforce role-based permissions. Raw electroporation data—including instantaneous current decay curves and calculated field strength (V/cm)—are retained with metadata (operator ID, date/time, sample ID, electrode type) to satisfy traceability needs in GLP or preclinical study reporting. Optional API integration enables bidirectional communication with laboratory information management systems (LIMS) and electronic lab notebooks (ELN).
Applications
- High-efficiency transfection of hard-to-transfect primary human T cells for CAR-T and TCR-engineered cell therapy development
- CRISPR-Cas9 RNP delivery into stem cells and organoids with reduced off-target editing and improved clonal recovery
- Large-scale electroporation of suspension bioreactor harvests for transient protein expression (e.g., monoclonal antibodies, viral vectors)
- In vivo plasmid DNA or mRNA delivery for DNA vaccine studies, tumor immunotherapy, and functional genomics in rodent models
- Electrofusion of hybridoma or dendritic–T cell conjugates for immunological synapse modeling
- Delivery of siRNA, antisense oligonucleotides, or CRISPR base editors into polarized epithelial monolayers
FAQ
Can the AgilePulse™ PLUS be used for in vivo electroporation in large animal models?
Yes—when paired with BTX’s CE-marked in vivo electrodes (e.g., BTX ECM 830 Needle Electrodes), the system supports subcutaneous, intramuscular, and intratumoral delivery in swine, non-human primates, and other preclinical species under institutional IACUC-approved protocols.
Is impedance monitoring available during pulse delivery?
The system does not provide real-time impedance feedback during pulsing; however, pre-pulse resistance measurement is performed automatically to confirm circuit continuity and approximate sample conductivity, preventing unsafe discharge conditions.
Does the AgilePulse™ PLUS support GMP manufacturing environments?
While the instrument is not supplied as a GMP-certified device, its design, documentation package (including IQ/OQ templates), and software audit trail capabilities enable qualification under client-specific validation protocols aligned with Annex 11 and ISO 13485 requirements.
What electrode types are validated for adherent-cell transfection?
BTX’s 96-well Plate Electrode (Model: PEP-96) and 24-well Adherent Cell Electrode (Model: ACE-24) are specifically characterized for direct transfection of confluent monolayers, with published transfection efficiencies exceeding 70% in primary keratinocytes and iPSC-derived cardiomyocytes.
How is pulse energy calculated and reported in the software?
Energy (Joules) per pulse is derived from measured voltage, current, and time integral (E = ∫V(t)·I(t) dt), and displayed alongside each pulse group in the protocol summary report—enabling cross-platform comparability with calorimetric or theoretical energy models.
