The relative fluorescence intensity of ANS-protein conjugates was measured using an PerkinElmer LS45 spectrofluorometer (American PerkinElmer Inc.) at excitation wavelength 365 nm and emission wavelength 480 nm.
After chromogen staining, the fluorescence of each well was measured in a spectrofluorometer (Thermo Scientific Lumina, USA) at 450 nm.
The implementation of fluorescence measurements was with the help of RF-5301PC spectrofluorometer (Shimadzu, Japan), and the slit width was 5.0 nm.
UV-vis spectra were obtained with a PerkinElmer Lambda 356 UV/VIS spectrophotometer, and emission measurements were performed on a Fluorolog-3 spectrofluorometer. [sup.1]H and [sup.13]C spectra were recorded on a Bruker avance DPX 400.
The instrument used was a spectrofluorometer (PerkinElmer Luminescence LS 55) capable of collecting excitation, emission, and synchronous spectra in the 200-800 nm range.
Similarly, a spectrofluorometer (PerkinElmer LS-55) was utilized to measure the fluorescence spectra over the range from 400 to 500 nm, and the wavelength of excitation was 355 nm.
Emission and excitation spectra were measured on QuantaMaster 40 steady state spectrofluorometer (Photon Technology International, Inc.).
Fluorescence of the released coumarin derivative was measured at 390/435 nm, using a Fluostar-BMG spectrofluorometer (Offenburg, Germany).
The intensity of fluorescence was quantified by using a dual-scanning microplate spectrofluorometer (Spectra MAX Gemini EM, Molecular Devices) at 480 nm excitation and 530 nm emission wavelengths.
The PerkinElmer model LS 55 was employed throughout this experiment; however, any other commonly available spectrofluorometer (Horiba, Hitachi, or Shimatsu), with dual gratings, one for excitation wavelength selection and another for emission band scanning, will be equally suitable.
