Customize Our Technology Solutions to Your Research Needs

Are constraints in lab resources, expertise, or time keeping you from making groundbreaking discoveries? Take your project forward with innovative near-infrared fluorescence imaging solutions for any leg of the relay: from bench to translational.

Chemistry and Conjugation Services

LI-COR IRDye® Infrared Dye fluorophores are enabling quantitative detection in biosciences: from in vitro assays, in vivo imaging and therapeutic applications, to investigational Phase I and II clinical trials.

  • LI-COR has been granted dozens of cyanine-based dye patents on composition of matter and methods in the United States and worldwide
  • More than 100 publications cite IRDye infrared dye products in therapeutic and diagnostic applications

See how you can answer complex research questions with our sensitive, quantitative, photo-stable dye technology.

Taking Compounds from Structures to Yield

Get on-demand synthesis of organic compounds; starting materials, intermediates, or derivatives, from milligram to multigram amounts. LI-COR Custom Services can also help you optimize syntheses and chemical modification reactions for small molecule compounds and dyes.

You can rely on our chemists’ expertise to label biomolecules, polymers, nanoparticles, and other compounds with IRDye fluorophores for sensitive detection of your assays. If you have other fluorescent or non-fluorescent labels and quenchers in mind, we can help you conjugate and optimize those, as well.

When you need to run a purity check or an ICH stability study for your compounds, our facilities are equipped to fulfill your project needs. We can also provide a complete analytical workup for your compounds.

Translational Services

LI-COR IRDye Infrared Dye fluorophores and the Pearl® Trilogy Small Animal Imaging Systems are enabling development of innovative diagnostic and therapeutic agents and optical imaging probes.

  • More than 300 publications cite the Pearl Small Animal Imaging Systems for in vivo imaging applications
  • Imaging agents conjugated to LI-COR IRDye infrared dye products are being investigated for human use in more than 16 active clinical trials (and counting…)

See how you can take your research from bench to clinic with our quantitative near-infrared fluorescence solutions.

Furthering Research Beyond the Bench

As you prepare to advance fluorophore-conjugated imaging and therapeutic agents to the clinic, place your confidence in the LI-COR Custom Services team. Through our experience in developing numerous IRDye-conjugated imaging agents, we have a thorough understanding of in vivo characterization, validation, and process optimization in small animals.

Bring the advantage of IRDye infrared dyes’ high signal-to-noise ratios, photo-stability, covalent conjugation, and clearance properties to visualize molecular targets and develop targeted therapies. We provide solutions and dual-mode imaging services on the Pearl Trilogy imager for efficient monitoring of optical agent biodistribution and localization in small animals.

IRDye fluorophore technology enables you to take imaging probes and agents systematically through in vitro, in vivo and ex vivo validation, then right into early phase clinical trials. Schedule a consultation to learn more about protocol optimization and validation best practices.

Manufacturing Services

LI-COR’s integrated chemical development and manufacturing services are helping bridge the gap between lab-scale and large-scale synthesis.

  • LI-COR has an on-site cGMP manufacturing facility
  • Our facilities are ISO 9001:2015 certified

Ask us about scale-up and transfer of your chemical synthesis protocols for research use, preclinical, and early-phase clinical projects.

Placing Large-Scale Synthesis Within Your Reach

Transfer of protocols and manufacturing of material for preclinical and clinical trial use is a high-risk venture. Let LI-COR Custom Services help you mitigate your risks with our scale-up and manufacturing services for IRDye infrared dyes, dye-conjugated probes, compounds, and active pharmaceutical ingredients (API) under current Good Manufacturing Practices (cGMP)*. For large and small-scale projects, you’ll get access to our state-of-the-art facilities, trained personnel, rigorous SOPs and quality standards to meet your goals.

Need custom synthesis for smaller-scale studies? Ask us about custom manufacturing services for research use only (RUO), and non-cGMP manufacturing for preclinical and toxicity studies. Our complete manufacturing solutions include analytical method development, manufacturing protocols, and stability studies under International Council for Harmonisation (ICH) guidelines.

We also provide custom reagent formulations and packaging, lyophilization services, and bulk quantities of our infrared dye and Western blotting reagents products.

* Products manufactured under cGMP are for investigational use only
