JY Series Universal Electrophoresis Power Supply (JY200C, JY300C, JY600C, JY1000C, JY1600C)

Overview

The JY Series Universal Electrophoresis Power Supply is a modular, microprocessor-controlled DC power source engineered for reproducible and safe operation across diverse electrophoretic techniques—including SDS-PAGE, native PAGE, isoelectric focusing (IEF), DNA agarose electrophoresis, electroblotting (wet, semi-dry, and tank transfer), and two-dimensional gel electrophoresis. Designed to meet the daily workflow demands of academic laboratories, core facilities, and QC/QA environments, each model delivers precise constant-voltage, constant-current, or constant-power output—enabling optimal separation resolution and transfer efficiency under variable buffer conductivity, gel thickness, and electrode configuration. The series supports standard mini-vertical gel cassettes (e.g., 8 × 10 cm), horizontal slab gels, and commercial blotting apparatuses without requiring external adapters or firmware updates.

Key Features

• Triple-mode output control: Independent selection of constant voltage (CV), constant current (CC), or constant power (CP) modes with real-time digital feedback and on-screen status indicators.
• Intelligent safety architecture: Automatic detection and shutdown for open-circuit (no-load), short-circuit, and over-temperature conditions; built-in thermal protection prevents component degradation during extended runs.
• Method memory bank: Stores up to 10 user-defined protocols—including voltage ramping profiles, stepwise current limits, and timed power cycles—with automatic recall and execution.
• Non-volatile parameter retention: All settings—including timer values, output mode, and setpoints—are preserved after power interruption or system reset.
• Ergonomic front panel: One-piece molded housing with tactile membrane keys and high-contrast backlit LCD (128 × 64 pixels) for legibility under low-light imaging hoods or darkroom conditions.
• Optional add-ons: Available factory-installed modules include power-fail recovery (resumes pre-interruption protocol upon reconnection) and field homogenization enhancement (minimizes lateral current dispersion in wide-format gels).

Sample Compatibility & Compliance

The JY Series interfaces seamlessly with widely adopted electrophoresis and transfer systems—including Bio-Rad Mini-PROTEAN®, Thermo Fisher Novex® XCell SureLock®, and GE Healthcare Hoefer® SE600 units—via standard banana-jack terminals (4 mm). It accommodates both aqueous and denaturing buffer systems (e.g., Tris-Glycine-SDS, Tris-Acetate-EDTA, CAPS-based IEF buffers) and maintains stable output across conductivity ranges from 0.5 to 25 mS/cm. While not certified to UL/CSA or IEC 61010-1 out-of-box, the units are manufactured under ISO 9001-certified quality management systems and comply with PRC GB/T 14710-2009 environmental testing standards for laboratory equipment. For GLP/GMP-regulated workflows, audit trails may be generated via optional RS-232 or USB data logging (firmware v2.3+), supporting basic 21 CFR Part 11 alignment when paired with validated third-party acquisition software.

Software & Data Management

The embedded firmware (v2.3 or later) supports ASCII-formatted serial output at 9600 baud via RS-232 port (DB9 male), enabling integration with LabVIEW, Python-based automation scripts, or custom LIMS interfaces. Real-time telemetry includes instantaneous voltage, current, power, elapsed time, and active mode—timestamped at 1-second intervals. No proprietary software installation is required; raw logs are compatible with Excel, OriginLab, or GraphPad Prism for post-run analysis. Firmware updates are performed via UART bootloader using standard FTDI adapters—documentation and HEX files are provided under NDA for institutional IT departments.

Applications

• High-fidelity protein separation in SDS-PAGE and BN-PAGE, particularly where consistent migration velocity and sharp band definition are critical for downstream mass spectrometry identification.
• Semi-dry and wet electroblotting of proteins onto PVDF or nitrocellulose membranes, with programmable voltage ramping to minimize heat-induced antigen denaturation.
• Agarose gel electrophoresis of genomic DNA fragments (0.2–20 kb), plasmid isolation, and PCR product verification under low-field conditions (≤5 V/cm).
• Two-dimensional electrophoresis (2-DE) first-dimension IEF runs requiring stable current delivery across pH gradients (e.g., IPG strips, 3–10 NL).
• Quality control of recombinant protein purity in biomanufacturing settings, aligned with USP and EP 2.2.47 electrophoretic assay guidelines.

FAQ

What electrophoresis techniques are supported by the JY Series?
The JY Series supports standard vertical and horizontal slab gel electrophoresis, electroblotting (wet, semi-dry, and tank transfer), isoelectric focusing, and two-dimensional electrophoresis—provided compatible electrophoresis chambers and buffer systems are used.
Is remote control or computer interfacing possible?
Yes—models with firmware v2.3+ support ASCII telemetry via RS-232 serial interface. USB-to-serial adapters enable connection to Windows/macOS/Linux hosts for automated logging and protocol scheduling.
Does the unit comply with FDA 21 CFR Part 11 requirements?
The hardware itself does not include electronic signature or audit trail generation natively; however, when integrated with validated third-party software that captures timestamped serial data, it can support Part 11 compliance in regulated environments.
Can the JY1000C safely operate high-voltage DNA sequencing gels?
Yes—the JY1000C (20–1000 V, 1–500 mA) is suitable for long-read DNA sequencing applications using polyacrylamide gels (e.g., 6–8% T, 29:1 C) under controlled cooling conditions; users must ensure adequate buffer circulation and temperature monitoring.
What is the warranty coverage and service support structure?
All JY Series units carry a 24-month limited warranty covering parts and labor. Technical documentation, firmware updates, and calibration procedures are accessible through authorized distributor portals—no region-locked licensing applies.
