Fluorescence technologies are widely used in diagnostics, detection, drug screening, and life science research. These methods rely on the excitation of a fluorescent compound by UV light and the emission of light at a lower energy. Two main types of fluorescent compounds are commonly used for bioconjugation: small organic fluorophores, such as fluorescein, and fluorescent proteins with covalently bound chromophores, such as phycobiliproteins. Both types can be conjugated to antibodies, proteins, and other biomolecules for detection applications.

Many fluorescent compounds are highly hydrophobic and chemically unstable, making labeling challenging. At CellMosaic, we have extensive experience in synthesizing fluorescent compounds and conjugating them to biomolecules. We can support customers with any specialized fluorescent labeling needs.
