BIOTRACKER FAR-RED PEROXYNITRITE LIVE CELL DYE

General description

Reactive oxygen species (ROS) and nitrogen species (RNS) are implicated in various physiological and pathological processes. Among ROS and RNS, peroxynitrite (ONOO−) has attracted much special attention because of the key roles that it plays in signal transduction and antimicrobial activities. Peroxynitrite is endogenously produced by reaction of nitric oxide (NO) and superoxide radical anion (O2), however, ONOO− is more cytotoxic than NO or O2 alone, contributing to numerous pathologies such as cardiovascular disease and injury, diabetes, and cancer.

The BioTracker Far-Red Peroxynitrite live cell dye can be used for ONOO- detection. This probe is cell permeable and displays a high sensitivity and selectivity towards peroxynitrite over other ROS/RNS.
This probe can be used to detect exogenous and endogenous peroxynitrite in living systems and displays long wavelength absorption (600 nm) and emission (638 nm) bands.
