BioLight WB-600Auto Automated Western Blot Processing System

Overview

The BioLight WB-600Auto Automated Western Blot Processing System is an engineered solution for standardized, high-reproducibility immuno-detection workflows in molecular biology and protein research laboratories. It replaces manual membrane handling during post-transfer steps—including blocking, primary/secondary antibody incubation, washing, and stripping—by integrating precise fluidics, temperature-controlled incubation, and programmable agitation into a single platform. Based on peristaltic pump-driven reagent delivery and multi-channel independent chamber architecture, the system operates on the principle of controlled volumetric dispensing and timed sequential perfusion, ensuring uniform reagent coverage and consistent dwell times across membranes. Designed for integration into academic, pharmaceutical, and clinical research settings, the WB-600Auto supports end-to-end automation of Western blot processing without requiring proprietary consumables or software lock-in.

Key Features

• Fully automated operation: Eliminates manual pipetting, timing, and washing steps—reducing hands-on time from hours to under 5 minutes per run.
• High-throughput capability: Simultaneous processing of up to six membranes in independently addressable chambers, each configurable with distinct protocols.
• 30 dedicated peristaltic pumps: Enable precise, cross-contamination-free reagent delivery for blocking, primary/secondary antibodies, wash buffers, and stripping solutions.
• Refrigerated reagent storage (4–10 °C): Preserves thermolabile antibodies and enhances reagent shelf life; supports automatic recirculation and reuse of expensive reagents including primary antibodies and blocking agents.
• Temperature-controlled incubation: Optional low-temperature module maintains incubation chamber at 4–15 °C, enabling overnight primary antibody binding with improved signal-to-noise ratio and reduced non-specific binding.
• Programmable touchscreen interface: Stores multiple user-defined protocols; allows granular control over dispensing volume (µL), incubation duration (min), agitation frequency (rpm), oscillation amplitude, and wash cycle count.
• Dual-format incubation compatibility: Accommodates standard 88 × 88 mm cassettes and narrow-format gels/membranes (58 × 88 mm and 28.5 × 88 mm); includes 12 pre-supplied incubation trays (6 of each size).

Sample Compatibility & Compliance

The WB-600Auto accepts nitrocellulose (NC) and polyvinylidene difluoride (PVDF) membranes following standard electrophoretic transfer (wet, semi-dry, or rapid transfer methods). It is compatible with all common blocking agents (BSA, non-fat dry milk, casein), primary and secondary antibodies (HRP- and fluorescent-conjugated), and commercial ECL and fluorescence-based detection reagents. The system’s hardware and firmware architecture support traceable, repeatable execution aligned with Good Laboratory Practice (GLP) requirements. Protocol logs—including timestamps, reagent lot numbers (manually entered), operator ID, and parameter settings—are retained locally and exportable as CSV or PDF for regulatory review. While not certified under FDA 21 CFR Part 11 out-of-the-box, the system’s audit trail functionality provides foundational infrastructure for labs implementing electronic signature and data integrity controls.

Software & Data Management

The embedded Linux-based operating system features a responsive 10.1-inch capacitive touchscreen with intuitive icon-driven navigation. Users create, save, duplicate, and archive protocols using a hierarchical menu structure. Each protocol defines discrete steps: reagent selection (mapped to physical pump positions), volume dispense (10–5000 µL range), incubation duration (1 sec to 99 hr), agitation profile (on/off, speed, duration), and wash iterations (1–20 cycles). All executed runs generate timestamped log files containing full parameter history, error codes (e.g., pump occlusion, low reagent level), and completion status. Data export is supported via USB 3.0 port; no cloud connectivity or remote access is implemented—ensuring local data sovereignty and compliance with institutional IT security policies.

Applications

The WB-600Auto is routinely deployed in target validation studies, biomarker verification, post-translational modification analysis (e.g., phosphorylation, ubiquitination), and QC testing of recombinant proteins. Its high reproducibility makes it suitable for longitudinal studies where inter-operator variability must be minimized—such as monitoring MMP9 expression dynamics in HepG2 hepatocellular carcinoma lysates under varying hypoxic or drug-treated conditions. In core facilities, the system enables shared-resource scheduling across multiple users without cross-experiment interference. It also serves as a bridge between discovery-phase Western blotting and regulated environments requiring documented, repeatable immunoassay procedures prior to ELISA or MSD method transfer.

FAQ

Does the WB-600Auto require proprietary reagents or consumables?
No. It uses standard laboratory-grade reagents and membranes; no vendor-specific kits or cartridges are needed.
Can I recover and reuse primary antibodies during incubation?
Yes. The system supports closed-loop recirculation of primary antibodies with optional refrigerated storage, extending usable life and reducing cost per assay.
Is the instrument compatible with fluorescent Western blot detection?
Yes. All incubation and wash steps are compatible with IRDye®, Alexa Fluor®, and other near-infrared or visible fluorescent conjugates.
How is maintenance performed?
Pump tubing is user-replaceable; calibration is performed automatically during startup via flow-rate verification against factory-set thresholds. A built-in diagnostic mode validates each pump and sensor channel.
What safety certifications does the device hold?
It complies with IEC 61010-1:2010 for electrical safety in laboratory equipment and meets CE marking requirements for electromagnetic compatibility (EMC) and low-voltage directive (LVD).
