Kinetics of the NIR-BG probe activation by β-gal. (a) Exitation and (b) Emission of 5 μM NIR probe in the presence of β-gal (10 U/mL), λex = 680 nm, λem = 700 nm. (c) Time-dependent fluorescence intensity increment at 700 nm using β-gal (0.1 U/mL) with different amounts of probes. λex = 680 nm; λem = 700 nm. (d) Lineweaver-Burke plot of the probe activation by β-gal.
