Invitrogen iBright CL1000 Smart Gel Imaging System

Overview

The Invitrogen iBright CL1000 Smart Gel Imaging System is a high-performance, chemiluminescence-optimized imaging platform engineered for reproducible detection and quantitative analysis of Western blots, nucleic acid gels, and stained protein gels. Built upon a cooled monochrome CCD architecture with a 1-inch sensor and ultra-fast f/0.95 fixed-focus lens, the CL1000 delivers exceptional photon capture efficiency—critical for low-signal chemiluminescent substrates such as HRP- or AP-conjugated antibodies. Unlike conventional UV transilluminators, the system employs a narrow-band green LED excitation source (peak ~525 nm), enabling safe, non-mutagenic visualization of SYBR Safe, SYBR Gold, and other green-fluorescent nucleic acid dyes without ozone generation or operator exposure risk. Its integrated 12-inch multi-touch display supports real-time image manipulation—including pinch-to-zoom, pan, and swipe-based navigation—eliminating dependency on external PCs during routine acquisition.

Key Features

• Cooled 9.1-megapixel monochrome CCD sensor with 16-bit analog-to-digital conversion, ensuring high dynamic fidelity across low- and high-intensity signal regions
• f/0.95 25 mm fixed-aperture lens optimized for maximum light throughput and uniform field illumination across the full imaging area
• Large-format imaging stage supporting simultaneous acquisition of up to four mini-gels (e.g., 8 × 10 cm) or two midi-gels (e.g., 13.5 × 16 cm), minimizing batch processing time
• Green LED transillumination module compliant with IEC 62471 Photobiological Safety standards; eliminates UV-associated DNA damage and user safety protocols
• Smart Explore™ automated workflow: one-touch optimization of exposure time, focus, zoom level, gel alignment, and background subtraction—reducing inter-user variability
• On-device touchscreen interface with intuitive gesture controls and embedded preview histogram for immediate exposure assessment

Sample Compatibility & Compliance

The CL1000 accommodates standard electrophoresis formats including polyacrylamide (SDS-PAGE, native PAGE), agarose, and gradient gels—both wet and dried. It supports detection modalities spanning chemiluminescence (ECL, ECL Prime, Luminata Forte), fluorescence (SYBR Safe, Ethidium Bromide alternatives, Cy dyes), and colorimetric stains (Coomassie, silver). All image metadata—including exposure parameters, lens settings, date/time stamps, and instrument firmware version—are embedded in TIFF and PNG exports per DICOM and MIAME-compliant conventions. Data integrity is reinforced through Thermo Fisher Cloud’s encrypted HTTPS transmission, role-based access control, and optional 21 CFR Part 11–compliant electronic signature modules for regulated environments.

Software & Data Management

iBright Analysis Software operates natively within the Thermo Fisher Cloud ecosystem, enabling browser-based access from any location with internet connectivity. Core analytical functions include lane and band detection, molecular weight estimation using internal calibration ladders, relative quantification via pixel-density integration, and batch normalization across multiple runs. Export options include publication-ready TIFF/PNG with embedded scale bars, CSV-formatted intensity tables, and annotated PDF reports. Instrument telemetry—including uptime logs, firmware revision history, and user session records—is accessible via Thermo Fisher Connect, facilitating preventive maintenance scheduling and laboratory equipment asset tracking aligned with ISO/IEC 17025 quality management requirements.

Applications

• Quantitative Western blot analysis for target protein expression profiling under dose-response or time-course experimental designs
• Verification of CRISPR/Cas9 editing efficiency via fragment size shift detection in T7E1 or Surveyor assays
• High-throughput validation of siRNA/shRNA knockdown efficacy across cell line panels
• Quality control of plasmid prep yields and restriction digest completeness prior to sequencing or cloning
• Documentation and archiving of electrophoretic results in GLP-compliant toxicology or biopharmaceutical stability studies

FAQ

Does the CL1000 support dual-mode imaging (chemiluminescence + fluorescence) in a single acquisition cycle?

No—chemiluminescent and fluorescent imaging require separate acquisition modes due to fundamental differences in excitation source configuration and filter positioning. However, both modalities are fully supported via software-selectable presets.
Can raw image files be exported in vendor-neutral formats compatible with third-party analysis tools?

Yes—TIFF (uncompressed, 16-bit), PNG (lossless compression), and CSV (intensity matrix) exports are available without proprietary wrappers.
Is local network deployment of iBright Analysis Software possible without cloud connectivity?

The software is exclusively cloud-hosted; offline operation is not supported. A stable internet connection is required for authentication, license validation, and data synchronization.
What is the expected operational lifetime of the green LED light source?

Rated for >20,000 hours of continuous use under standard laboratory conditions (25°C ambient, 50% duty cycle), with minimal spectral drift over time.
How does the system ensure traceability for regulatory submissions?

All acquisitions generate immutable audit trails—including timestamps, user IDs, instrument serial numbers, and parameter configurations—exportable as PDF reports with digital signatures enabled via Thermo Fisher Cloud’s Part 11 add-on module.
