FLUOROGENIC PH SENSITIVE DYES AND THEIR METHOD OF USE

A new class of pH sensitive fluorescent dyes and assays relating thereto are described. The dyes and assays are particularly suited for biological applications including phagocytosis and monitoring intracellular processes. The pH sensitive fluorescent dyes of the present invention include compounds of Formula (I), wherein the variables are described throughout the application.

Non-fluorescent quencher compounds and biomolecular assays

Bis-diazo,triaryl and aryldiazo-N-arylphenazonium quencher moieties, substituted with electron-withdrawing and electron-donating substituents which induce polarity in the delocalized aryl/diazo ring systems, are useful as labels when attached to biomolecules such as polynucleotides, nucleosides, nucleotides, and polypeptides. The quencher moieties are non-fluorescent and accept energy from fluorescent reporter labels by any energy-transfer mechanism, such as FRET. Fluorescence quencher compositions are useful in preparing quencher labelled biomolecules for various molecular biology assays based on fluorescence detection.
