ddao

DDAO is a promising near-infrared (NIR) red fluorescent probe with a long emission wavelength (λem = 656 nm) and a tunable excitation wavelength (600-650 nm). It can be designed for detecting the activities of various enzymes such as β-galactosidase, sulfatase, protein phosphatase 2A, carboxylesterase 2, human albumin, and esterases.

DDAO-C6, a cridone ester derivative, serves as a highly specific fluorescent probe for detecting human serum albumin (HSA). Additionally, it functions as an enzymatically activatable near-infrared fluorescent probe, facilitating the visual detection of endogenous lipase produced by gut microbes (Ex/Em=600/658 nm) [1] [2].

DDAO phosphate diammonium serves as a fluorescent phosphatase substrate with a tunable excitation wavelength (600-650nm) and a long emission wavelength (λem=656nm). It is effective for detecting the activity of various enzymes including β-galactosidase, sulfatase, protein phosphatase 2A, carboxylesterase 2, human albumin, and esterase.
