Fluorescein emission spectrum
Did you know?
Fluorescein is a fluorophore commonly used in microscopy, in a type of dye laser as the gain medium, in forensics and serology to detect latent blood stains, and in dye tracing. Fluorescein has an absorption maximum at 494 nm and emission maximum of 512 nm (in water). The major derivatives are fluorescein isothiocyanate (FITC) and, in oligonucleotide synthesis, 6-FAM phosphoramidite. In cellular biology, the isothiocyanate derivative of fluorescein is often used to label and track cells in fluorescence … WebThe emission spectrum is usually sharper than the excitation spectrum, and it is of a longer wavelength and correspondingly lower energy. Excitation energies range from ultraviolet through the visible spectrum, ... Xanthene derivatives: fluorescein, rhodamine, Oregon green, eosin, and Texas red;
WebThe excitation and emission spectra for fluorescein were compared against the results obtained with a reference instrument, LS 55 Fluorescence Spectrometer. The acquired spectral profiles and peak wavelengths are well aligned with a peak excitation at 490 nm and emission at 513 nm (Fig. 5). Figure 2. EnVision Manager settings for running a ... WebFluorescein is a fluorescent compound with an excitation peak at 498 nm and an emission peak at 517 nm. It can be excited using a 488 nm laser paired with a 525/50 nm bandpass filter, a configuration that can be found, for example, in the BD Special Order …
WebThe Alexa Fluor 488 detection channel (see Figures 1(a) and 1(d)) photomultiplier slit has been set to a 30-nanometer bandwidth (ranging from 500 to 530 nanometers) that encompasses the primary probe emission peak, but does not capture a significant amount of fluorescence from Cy3 emission. WebFluorescence spectra of irbesartan were recorded on a JASCO FP-8200 Fluorescence Spectrometer (JASCO Corporation, Osaka, Japan) equipped with a 150 W xenon lamp …
WebFeb 11, 2014 · Fluorescence measurements were performed by using a FLS 920 fluorospectrometer of Edinburgh Instruments with cuvettes of 1 cm and excitation at 500 nm (20 °C). The emission slit was 1.0 nm while the excitation slit was 0.5 nm. The fluorescence was measured at 90° to the incident excitation beam.
