1,8-Diazafluoren-9-one (DFO) is an aromatic ketone first synthesized in 1950. It is used to find fingerprints on porous surfaces. It makes fingerprints glow when they are lit by blue-green light. DFO reacts with amino acids present in the fingerprint to form highly fluorescent derivatives. Excitation with light at ~470 nm results in emission at ~570 nm. WebOxidative Stress Detection Reagent (Green) ROS Inducer (Pyocyanin) Hypoxia Inducer (DFO) Technical Info/Product Notes: The ROS-ID ® Hypoxia/Oxidative stress detection kit is a member of the CELLESTIAL ® product line, reagents and assay kits comprising fluorescent molecular probes that have been extensively benchmarked for live cell …
