Discovering a Dihydrofluorescein Analogue as a Promising Fluorescence Substrate to HRP

چکیده

Horseradish peroxidase (HRP) combined with its fluorescence substrates is attracting increasing attention for biochemical analysis. Amplex red the most widely used substrate to HRP; however, it suffers from some drawbacks, such as nonspecific responsiveness toward carboxylesterases. Discovering a new small molecular improved sensitivity and selectivity HRP thus desired. Herein, three dihydrofluorescein derivatives (DCFHs) are presented serve through turn-on methods. The promising one, 2,7-dichloro-9-(2-(hydroxymethyl)phenyl)-9H-xanthene-3,6-diol (DCFH-1), exhibited excellent in detection of HRP. Moreover, DCFH-1 does not respond carboxylesterase, holding advantages over red. In further study, reagent commercial ELISA kits was replaced establish ELISA, which works very well quantification inflammatory cytokine biomarkers vitro models.

Picosecond time-resolved fluorescence of ribonuclease T1. A pH and substrate analogue binding study.

The tryptophyl fluorescence of ribonuclease T1 decays monoexponentially at pH 5.5, tau = 4.04 ns but on increasing pH, a second short-lived component of 1.5 ns appears with a midpoint between pH 6.5 and 7.0. Both components have the same fluorescence spectrum. Acrylamide quenches both fluorescence components, and the short-lived component is quenched fivefold faster than the predominant long co...
