Description

Quantity: 1 mg
Unit Size: Each
DAF-FM is essentially nonfluorescent until it reacts with NO to form fluorescent benzotriazole. DAF-FM fluorescence can be detected by any instrument that can detect fluorescein, including flow cytometers, microscopes, fluorescent microplate readers and fluorometers.
• Ex/Em of DAF-FM: approx. 495/515nm
• Lyophilized product should be dissolved using DMSO and then added to an aqueous buffer to create a working solution
• DAF-FM can be introduced into cells by pressure injection or perfusion from patch-clamp pipette
• Buffers containing bovine serum albumin (BSA) and phenol red may affect the fluorescence and should be used with caution
• Fluorescence quantum yield of DAF-FM is ∽0.005, but increases about 160-fold, to ∽0.81, after reacting with NO
• Assessment of NO production in transaldolase-deficient lymphoblasts by flow cytometry
• Detection of NO accumulation in embryonic cortical neurons following neurotrophin stimulation
• in vivoimaging of NO in zebrafish
• Intravital microscopic detection of NO generation associated with angiogenesis in mice
• Quantitation of ATP-induced NO release in rabbit platelets
• Spectra of NO adduct of DAF-FM are independent of pH above pH 5.5
• NO adduct of DAF-FM is significantly more photostable than that of DAF-2, which means additional time for image capture
• DAF-FM is more sensitive reagent for NO than is DAF-2 (NO detection limit for DAF-FM approx. 3nM versus approx. 5nM for DAF-2)Refer to the Molecular Probes™ Handbook for additional product information.Anion Detection, Cell Analysis, Cell Metabolism, Cell Viability, Proliferation and Function, Ionic Homeostasis and Signaling, Nitric Oxide Research, Nitro-Oxidative Stress
