Fluorescent Dyes

The roots of the Company are in the imaging business where we have provided fundamental contribution to the growth and the global adoption of diagnostic medical imaging, color photography, and printing systems.

We have been mastering the interactions between photons and chemicals for almost a century. At Ferrania Chemicals, we believe it takes an imaging expert to understand and address your fluorescence needs!

Ferrania Chemicals is an established player in an exciting technology, based on light radiation applied to biomedical research and diagnostic chemistry, in the quest for better markers to define molecular content, activity and dynamics in countless applications in Life Sciences.

Home to the leaders in photoimaging technology, our labs are fully equipped to identify, synthesize and provide the best materials in a broad range of applications such as: Fluorescence Flow Citometry, Fluorescence-Activated Cell Sorting, Fluorescence Microscopy, Fluorescence Immunoassay, Fluorescence Staining, Genetic studies and Fluorescence Resonance Energy Transfer applications.

Ferrania Chemicals Fluorescent Dyes are designed to ensure:     

  • No background fluorescence
  • Conjugation with target materials with no shift in the fluorescence of the dye
  • High quantic yield and fluorescence intensity
  • High molar extinction coefficients
  • Negligible photobleaching
  • Highly hydrophilic properties, especially in physiological solutions

 

Passion for Partnering

We are deploying the best of our R&D efforts to offer superior labeling dyes. Our drivers are the needs of our customers and partners: we are ready to be by your side providing solutions to your requirements, partnering with you in research, supporting your growth by custom synthesis.
