Abcam, ab146631, DAF-2 DA (DMSO solution), fluorescent nitric oxide probe

Size: 100µg
MW 446.4 Da, Purity >98%. Fluorescent nitric oxide probe; membrane-permeable. Once inside cell it reacts with NO in the presence of oxygen to yield the highly fluorescent triazolofluorescein DAF-2T (ab145473). Determines nitric oxide synthase activity. Has a 2-5 nM detection limit at neutral pH. Also available as a solid (ab145283).
