The effect of the binding of β-galactosidase on the emission spectra of AEDANS-M469C in refolding buffer. β-Galactosidase denatured with 8 M urea was diluted 50-fold into refolding buffer, in which 0.2 μM AEDANS-M469C and 0.8 M urea were present at 10°C. The final concentration of β-galactosidase was 17.2 μM.
