The analytes were detected by using fluorescence detection at an excitation and emission wavelength of 288 and 478 nm, respectively.
In particular, noninvasive label-free imaging capability of TPEF microscopy can be achieved by using the fluorescence emission from the endogenous fluorescent molecules in living cells and tissue, such as the reduced nicotinamide adenine dinucleotide (NADH), tryptophan, flavin adenine dinucleotide (FAD), keratin, collagen and elastin etc.
The ROS level was examined by detecting the fluorescence intensity using fluorescence microscope and microplate reader with excitation an emission wavelengths set at 500 and 529 nm, respectively.
The red fluorescence (excitation 550 nm, emission 600 nm) and green fluorescence (excitation 485 nm, emission 535 nm) were measured using fluorescence Thermo Scientific Varioskan Flash Multimode plate reader.
The drop was taken by 1 ml of acetonitrile solvent compatible high performance liquid chromatography by which the extracts were analyzed using a fluorescence emission detector (Waters 2475).
Samples were examined by confocal microscopy (DM1RE-2, Leica Mikrosysteme, Wetzlar, Germany) using appropriate fluorescence emission filters.
However, given that protein folding is usually accompanied by changes in the emission of tryptophan fluorescence, label-free MST instruments allow denaturant titrations to also be measured using intrinsic fluorescence emission.
Fluorescence emission was measured by using a fluorescence microplate (TECAN, infinite F200 PRO) with an excitation at 494 nm and emission at 516 nm.
Fluorescence emission was measured by using a fluorescence microplate (TECAN, infinite F200 PRO, Mannerdorf, Switzerland).
