Fluorescent Dyes, or fluorophores, Fluorescent Probes & Stains,  are compounds that absorb light at a given wavelength and emit light at a higher wavelength, producing fluorescence. These fluorescent dyes can be grouped into categories, such as organic dyes (e.g., fluorescein, rhodamine, AMCA), biological fluorophores (e.g., green fluorescent protein, phycoerythrin, allophycocyanin), and quantum dots. They are often used in the fluorescent labeling of biomolecules. They are smaller and more photostable than fluorescent proteins.

AxisPharm offers a full spectrum of ready-to-conjugate dyes to researchers for their biomolecule conjugation and applications.

Our Fluorescent dyes are furnished with a wide range of reactive functional groups, such as succinimidyl ester (SE/NHS ester), maleimides, free acids, and click chemistry handles. We offer one of the most comprehensive collections of copper-free bioorthogonal click chemistry tools, such as azide, alkyne, TCO, tetrazine, BCN, and DBCOs.
