Do you need bulk/larger quantities?
Cell permeable analog of DAF-2 (Prod. No. ALX-620-052) that is hydrolyzed to DAF-2 by intracellular esterases. Can be used in fluorescence microscopy to measure real-time changes in nitric oxide (NO) levels in vivo (Ex(max): 495nm; Em(max): 515nm).

DAF-2 DA (cell permeable) image
Figure: The cell-permeable diacetate derivative, DAF-2 DA (Prod. No. ALX-620-056), is used to load cells. Subsequent hydrolysis by cytosolic esterases releases DAF-2 (Prod. No. ALX-620-052), which is relatively non-fluorescent at physiological pH. However, in the presence of NO and O2, DAF-2 is converted to the fluorescent triazole derivative, DAF-2T (Prod. No. ALX-620-060)."
