DAF-2 diacetate (Synonyms:4,5-二氨基荧光素二乙酸酯)
目录号 : KCM12437 CAS No. : 205391-02-2 纯度 : ≥95%
DAF-2 diacetate is a sensitive fluorescent indicator for the detection and bioimaging of nitric oxide (NO). It is a cell-permeable derivative of DAF-2. Upon entry into the cell, DAF-2 diacetate is transformed into the less cell-permeable DAF-2 by cellular esterases thus preventing loss of signal due to diffusion of the molecule from the cell. In the presence of oxygen, DAF-2 reacts with NO to yield the highly fluorescent triazolofluorescein (DAF-2T). Fluorescence is monitored using excitation and emission wavelengths of 485 and 538 nm, respectively. At neutral pH the detection limit for NO is 2-5 nM. DAF-2 diacetate can be utilized in cells which produce small amounts of NO, such as endothelial cells, as well as in cells which generate large amount of NO, such as macrophages.
