Clinx IVScope 7500 Plant In Vivo Imaging System

Overview

The Clinx IVScope 7500 Plant In Vivo Imaging System is a purpose-built, high-sensitivity optical detection platform engineered for non-invasive, longitudinal monitoring of biological processes in intact, living plants. Operating on the principles of low-light photon detection and spectral separation, the system integrates a back-illuminated, thermoelectrically cooled CCD sensor with an ultra-fast f/0.8 lens assembly housed within a light-tight imaging chamber. This architecture enables quantitative capture of weak bioluminescent signals—such as those from luciferase reporters—and multi-channel fluorescence emissions—including GFP, RFP, YFP, and near-infrared probes—across developmental timecourses. Unlike conventional microscopes or plate readers, the IVScope 7500 maintains physiological relevance by supporting whole-plant imaging under controlled environmental conditions, making it suitable for studies requiring sustained observation without sample disruption.

Key Features

• Back-illuminated 1 MP CCD sensor with 13 µm × 13 µm pixel pitch, delivering enhanced quantum efficiency (>95% at 600 nm) and reduced read noise for optimal signal-to-noise ratio in low-photon environments.
• f/0.8 motorized lens with precise autofocus and fixed focal length—engineered to maximize photon collection efficiency while maintaining uniform field illumination and minimal optical distortion.
• Deep-cooling capability down to −90 °C (with optional recirculating chiller), significantly suppressing dark current and enabling integration times up to 30 minutes without thermal noise saturation.
• Modular illumination architecture: standard white-light reflectance module; optional UV/visible/NIR excitation sources; and configurable RGBW LED arrays for programmable photoperiod simulation and circadian rhythm assays.
• Motorized Z-axis sample stage with programmable height presets—ensuring repeatable positioning across sequential imaging sessions and facilitating multi-angle acquisition when combined with the optional lateral imaging module.
• Expandable optical path: motorized filter wheel supports up to 6 emission filters (e.g., 510/20 nm, 580/30 nm, 700/40 nm), enabling multiplexed reporter quantification and spectral unmixing workflows.

Sample Compatibility & Compliance

The IVScope 7500 accommodates a broad range of plant specimens—from Arabidopsis seedlings and rice tillers to tomato fruit clusters and maize seedlings—within its standardized imaging chamber (internal dimensions: 35 cm W × 35 cm D × 50 cm H). The optional integrated temperature and humidity control unit maintains setpoints between 15–35 °C and 40–90% RH with ±0.5 °C and ±3% accuracy, satisfying requirements for long-term phenotypic monitoring under defined growth conditions. All hardware and software components are designed in alignment with Good Laboratory Practice (GLP) documentation standards. Audit trail functionality, user access controls, and electronic signature support are embedded in the optional touch-screen acquisition software—facilitating compliance with FDA 21 CFR Part 11 for regulated research environments.

Software & Data Management

Acquisition and analysis are performed using Clinx ImageStudio Pro—a dedicated, Windows-based application developed for plant-specific imaging workflows. The software provides real-time preview, automated exposure optimization, background subtraction, flat-field correction, and region-of-interest (ROI) based radiance quantification (photons/sec/cm²/sr). Time-series data are stored in vendor-neutral HDF5 format with embedded metadata (exposure time, filter ID, temperature, humidity, stage position). Batch processing pipelines support normalization across replicates, kinetic curve fitting, and export to CSV, TIFF, or MATLAB-compatible structures. Raw image archives include full EXIF-equivalent headers compliant with MIAPPE (Minimum Information About a Plant Phenotyping Experiment) guidelines.

Applications

• Temporal profiling of promoter activity via luciferase or fluorescent protein reporters during germination, flowering, and senescence.
• Quantitative assessment of pathogen colonization dynamics (e.g., Pseudomonas syringae, Botrytis cinerea) using luminescent or fluorescent bacterial strains.
• In vivo validation of protein–protein interactions via split-luciferase or BiFC assays under native tissue context.
• Circadian gating experiments enabled by synchronized RGBW lighting and continuous imaging over 72+ hours.
• Abiotic stress response mapping—including drought, salinity, and oxidative stress—through spatially resolved reporter activation patterns.
• Root–shoot signaling studies using dual-wavelength fluorescence to distinguish apoplastic vs. symplastic transport routes.

FAQ

What is the minimum detectable photon flux for bioluminescence imaging?
The system achieves a theoretical detection limit of ≤100 photons/sec/cm² under optimal cooling and integration conditions—validated using calibrated luminophore standards traceable to NIST SRM 2211.
Can the IVScope 7500 be used for root imaging in soil or hydroponic systems?
Yes—compatible with transparent rhizoboxes, agar plates, and aeroponic mist chambers; optional side-view module enables orthogonal imaging of root architecture without repositioning.
Is the software compatible with third-party analysis tools such as FIJI/ImageJ or Python-based pipelines?
All exported TIFF and HDF5 files retain calibrated intensity values and metadata headers, enabling direct ingestion into open-source platforms with no proprietary codec dependencies.
Does the system support kinetic imaging over multiple days without manual intervention?
Fully automated time-lapse protocols—including stage movement, filter switching, exposure adjustment, and environmental parameter logging—can be scheduled for uninterrupted operation up to 14 days.
How is calibration maintained across imaging sessions?
A built-in reference LED source and certified neutral-density filters enable daily photometric recalibration; drift correction algorithms compensate for minor sensor sensitivity shifts over extended runs.
