Dyomics® Fluor Listing

Dyomics® fluorescent dyes are a family of high-performance fluorophores developed by Dyomics GmbH for advanced biological labeling applications. These dyes offer excellent brightness, high photostability, low nonspecific background, and broad spectral coverage from the ultraviolet to near-infrared regions. Dyomics® dyes are widely used for labeling DNA, RNA, PNA, peptides, proteins, antibodies, and other biomolecules for applications including fluorescence microscopy, flow cytometry, qPCR, FISH, confocal microscopy, super-resolution imaging, and in vivo fluorescence imaging

MegaStoke Dye Family

MegaStokes™ fluorescent dyes are designed with exceptionally large Stokes shifts, enabling excitation at one wavelength and fluorescence emission hundreds of nanometers away. Compared with conventional fluorophores, MegaStokes™ dyes minimize excitation light bleed-through, reduce background fluorescence, and simplify multiplex assay design. Dyomics offers three MegaStokes™ families—UV-MegaStokes™, MegaStokes™, and NG-MegaStokes™—covering UV, visible, and next-generation high-performance fluorophores for advanced imaging, diagnostics, and molecular labeling applications.

Why are MegaStokes™ dyes useful?

Traditional fluorescent dyes have relatively small Stokes shifts (typically 20–40 nm), so the excitation light and emitted fluorescence are close together spectrally. This can lead to:

• excitation light bleed-through
• increased background fluorescence
• more complex optical filter requirements

MegaStokes™ dyes solve these issues by emitting far away from their excitation wavelength.

Benefits

• Extremely large Stokes shifts
• Low background fluorescence
• Minimal excitation bleed-through
• Simplified optical filter design
• Ideal for multiplex fluorescence assays
• Multiple emission colors from a single excitation laser
• Excellent for fluorescence microscopy, flow cytometry, FRET, and diagnostic assays

One small note:

NG-MegaStokes™ excitation/emission values should be verified against the latest Dyomics datasheets before publication, but the overall organization and closest-emission matches are exactly how I would present them on the website.
