    Innovative Answers to
    Biomedical Questions

    Whether you are monitoring the molecular basis of disease, or developing efficient drug delivery systems, targeted therapies and surgical contrast agents, quantitative near-infrared detection will help you find solutions to your complex research questions.

    Explore Molecular Imaging Probe Development with LI-COR Near-Infrared Technology

    Probe Design

    Convert your targeting molecules into reporter-labeled probes and agents with IRDye® infrared dye fluorophores, or ask us about our services for synthesis and bioconjugation.

    Probe Validation

    Validate your dye-conjugated probes and agents in vitro, in vivo, and ex vivo with Odyssey® CLx and Pearl® Small Animal Imaging Systems, or schedule a consultation for your bioassay imaging needs with our biologists.

    Probe Manufacturing

    Get custom synthesis of your dye-conjugated probes and agents on a larger scale, and manufacturing (cGMP, non-cGMP) for clinical development with Custom Services.


    Shape your targeting molecules into functionalized imaging probes and agents. Start with reporter dyes that get you sensitive and consistent detection for in vitro and in vivo use. If clinical translation is on your horizon, evaluate dyes with potential for human use.

    Get One Step Ahead of the Game

    Take your imaging probes and agents from bench to clinic with a versatile reporter dye technology.

    IRDye infrared dye fluorophores provide exceptional sensitivity and high signal-to-noise ratios for detection and quantitation. That’s because the IRDye advantage lies in near-infrared detection, where light absorption by and autofluorescence from cellular and tissue components is low. So, imaging agents labeled with these fluorophores allow biochemical activity measurements of in vitro and in vivo assays with high-sensitivity.

    But that’s not all. IRDye 800CW and 700DX fluorophores have found applications in preclinical and clinical use. Probes and agents conjugated to these dyes have propelled more than 20 Phase I and Phase II clinical trials worldwide.

    Image in the NIR imaging window for optimal sensitivity. Hemoglobin (Hb) and other tissue components strongly absorb visible light. In the NIR region, tissue absorbance is dramatically reduced, allowing light to easily pass through the tissue. Above 820 nm, light absorbance by water begins to increase.

    “Among the fluorophores that we've used, the LI-COR dye, IRDye® 800CW seems to provide the ability to detect the tumors while maintaining suitable pharmacokinetics for use in vivo. It has worked quite well with our preclinical models.”

    Dr. Martin G. Pomper, Johns Hopkins Medical School


    Assess your molecular probe’s biological performance in vitro, in vivo, and ex vivo. Maximize your chances of success with a detection technology that will get you quantitative and consistent data.

    • Screen for specificity and binding affinity with in vitro cell-based assays, then move your ‘hits’ to animal studies with confidence
    • Evaluate the big picture pharmacology with biodistribution and clearance studies in vivo, then get one step deeper
    • Measure uptake and localization in tissues and organs ex vivo for a complete workup

    Robust Bioassay Imaging Solutions:

    Improve Productivity

    Use one powerful detection technology for all your bioassays.

    The Odyssey CLx Infrared Imaging System and the Pearl Trilogy Small Animal Imaging System provide an ideal near-infrared detection platform combination for complete analysis of your probe’s performance in vitro, in vivo, and ex vivo.

    Equipped with laser-based NIR detection, the versatile Odyssey CLx Imaging System platform allows accurate quantitation of minute biochemical responses in a variety of assay formats. That means you can expedite the screening process for target specificity and binding affinity using higher throughput cell-based assays like In-Cell Western™ and On-Cell Western.

    Engineered with single-camera optics and uniform illumination, the Pearl Trilogy provides an optimal imaging setup for small animal studies. The same laser-based NIR detection makes animal tissue virtually transparent, which aids greatly in tracking the biodistribution and clearance of probes and agents in vivo.

    With its 21 µm scanning resolution, the Odyssey CLx Imaging System lets you screen for probe uptake, localization, and biodistribution in tissue sections and organs excised from treated animals. This facilitates macroscopic analysis without the need for an additional near-infrared microscope.

    “Data from the Odyssey and Pearl Systems completely complement each other, which makes it easier to transition from cells to animals and back. We get more out of one animal compared to traditional methods.”

    Jelena Janjic, Duquesne University
