    Product Description

    CAY10732 is a fluorescent probe for the detection of carbon monoxide.1 In the presence of palladium (Pd) and carbon monoxide, CAY10732 undergoes the Pd0-mediated Tsuji-Trost reaction to release 2,7-dichlorofluorescein, and its fluorescence can be used to detect carbon monoxide production in vitro and in live cells. 2,7-Dichlorofluorescein displays excitation/emission maxima of 493/527 nm, respectively.

    WARNING This product is not for human or veterinary use.
