DLAB DL-ZY02 Mini Trans-Blot Electrophoresis Transfer Cell

Overview

The DLAB DL-ZY02 Mini Trans-Blot Electrophoresis Transfer Cell is a compact, benchtop electrophoretic transfer system engineered for rapid and reproducible semi-dry or wet-style protein transfer from polyacrylamide or agarose gels to solid supports—including nitrocellulose, PVDF, and nylon membranes. It operates on the principle of electrophoretic mobility under a controlled direct current (DC) field, enabling directional migration of denatured proteins from the gel matrix to the membrane surface with high retention efficiency. Designed specifically for small-format gels (up to 110 × 90 mm), the DL-ZY02 delivers consistent field uniformity across the transfer area due to its precisely spaced platinum electrodes (4 cm inter-electrode distance), minimizing edge effects and ensuring even current density—critical for preserving epitope integrity and downstream immunodetection sensitivity.

Key Features

• Compact footprint optimized for space-constrained laboratories and shared core facilities—ideal for routine Western blotting workflows.
• High-transparency polycarbonate housing enables real-time visual monitoring of buffer levels, gel alignment, and bubble formation during transfer setup.
• High-purity platinum wire electrodes ensure low-resistance current conduction, minimal electrolysis byproduct generation, and long-term corrosion resistance—even under repeated high-current operation.
• Color-coded clamps (red/black) and electrode terminals provide unambiguous anode/cathode orientation, eliminating risk of reversed polarity—a common cause of failed transfers or membrane damage.
• Integrated ice pocket accommodates standard laboratory ice cubes or pre-chilled cold packs, actively dissipating Joule heating generated during high-voltage transfer protocols (e.g., 25–30 V for 30–60 min).
• Chemically resistant construction withstands common transfer buffers (e.g., Tris-glycine-methanol, CAPS, or BIS-TRIS-based systems) without stress cracking or haze development over time.

Sample Compatibility & Compliance

The DL-ZY02 supports standard mini-gel formats used in SDS-PAGE (e.g., 8.3 × 7.3 cm, 10 × 8 cm) and native PAGE applications. Its 110 × 90 mm active transfer window accommodates most commercially available mini-transfer cassettes and custom-cut membranes. The unit complies with general electrical safety requirements per IEC 61010-1 for laboratory equipment. While not certified to ISO/IEC 17025 or GLP as a standalone analytical instrument, it is routinely employed in laboratories adhering to Good Laboratory Practice (GLP) and Good Manufacturing Practice (GMP) environments where traceable, documented transfer parameters (voltage, time, temperature) are maintained per internal SOPs aligned with FDA 21 CFR Part 11 data integrity expectations.

Software & Data Management

The DL-ZY02 is a manually operated, hardware-only electrophoretic transfer cell with no embedded microcontroller or digital interface. All operational parameters—including voltage, current, duration, and cooling protocol—are set externally via compatible power supplies (e.g., DLAB PS Series or third-party constant-voltage/current sources). Users maintain full experimental traceability through lab notebook entries or electronic lab notebook (ELN) systems, recording batch-specific conditions for each transfer run. No firmware updates, calibration certificates, or proprietary software drivers are required—ensuring compatibility with existing infrastructure and simplifying audit readiness.

Applications

• Routine Western blotting for qualitative and semi-quantitative protein detection in molecular biology and biomedical research labs.
• Optimization of transfer efficiency for low-abundance or high-MW proteins using variable voltage/time profiles.
• Validation of antibody specificity through parallel transfer of duplicate gels under identical conditions.
• Teaching laboratories requiring robust, intuitive instrumentation for undergraduate and graduate electrophoresis instruction.
• Preparative transfer prior to N-terminal sequencing or mass spectrometry analysis where membrane integrity and protein recovery yield are critical.

FAQ

What gel thicknesses are compatible with the DL-ZY02?

The unit accommodates standard 1.0 mm and 1.5 mm thick mini-gels; thicker gels (>1.5 mm) may impede uniform buffer contact and require extended transfer times.
Can the DL-ZY02 be used for nucleic acid transfer?

Yes—though optimized for proteins, it supports DNA/RNA transfer to positively charged membranes when paired with appropriate alkaline or neutral transfer buffers.
Is the ice pocket removable for cleaning?

No—the ice pocket is an integral molded feature of the polycarbonate base; cleaning is performed with 70% ethanol or mild detergent solution without disassembly.
Does DLAB provide validation documentation for GxP environments?

DLAB supplies material certification (RoHS, REACH) and mechanical drawings upon request; full IQ/OQ/PQ protocols must be developed internally per institutional regulatory requirements.
What power supply specifications are recommended?

A programmable DC power supply capable of 0–100 V and 0–1 A output, with voltage/current limiting and timer functions, is strongly advised for reproducible results.
