It has a broad spectrum of excitation with the main peak at 482 nm, and a long Stokes shift to an emission … As with our PE conjugates, an average of one PE-Cy5 molecule is coupled per antibody or protein. The excitation spectrum of a given fluorochrome is determined in a similar manner by monitoring fluorescence emission at the wavelength of maximum intensity while the fluorophore is excited through a group consecutive wavelengths. Within groups, roughly in order of excitation wavelength (families excepted). Here are some hints and tips on how to handle tandem dyes: Always protect tandem dyes from light as they are highly susceptible to photobleaching. Excitation & Emission Spectra PE/Dazzle™ 594 excites optimally at 566 nm and emits optimally at 610 nm. The fluorophores absorbance wavelength from 325nm to 743nm (from blue color to red color), the emission wavelength … Similarly, the light produced by fluorochromes has a range of wavelengths. tdTomato is a basic (constitutively fluorescent) orange fluorescent protein published in 2004, derived from Discosoma sp.. As demonstrated in Figure 1, the red-shifted variants, typified by EGFP, have a single excitation peak centered at about 488 nm, with an emission peak wavelength of 509 nm. However, the closer the excitation wavelength is to 495 nm, the more fluorescence will be produced. In general, the excitation peak wavelength does not change when the emission monochromator wavelength setting is changed, and vice versa, although this could be … Jackson ImmunoResearch offers the form found in Dinophyceae sp. Peak excitation and emission wavelengths often vary depending on the environment in which the probe finds itself. Fluorophores Absorption and Emission Data. The table lists the properties of the most commonly used fluorophore for peptide labeling of your interest in the life sciences. Excitation and emission spectra of Alexa Fluor ® 488, PE, PerCP-Cy5.5, and PE-Cy7 following excitation with the blue laser (488 nm). This optimal wavelength is called the excitation peak. Peridinin-Chlorophyll-Protein (PerCP) is a 35.5 kDa fluorescent peridinin-chlorophyll-protein complex isolated from dinoflagellates. So, for example, PE-Cy5 will excite at the excitation wavelength for PE (565 nm) and emit at the emission wavelength for Cy5 (670 nm). Electromagnetic energy from a laser set at the correct wavelength will provide the right amount of energy to an electron in the donor fluorescent dye molecule. The emission maximum is chosen and only emission light at that wavelength is allowed to pass to the detector. The emission of light from fluorescein, ranges from 490 nm to 630 nm, and the emission peak is approximately 520 nm. cytometry (e.g., RED613™ , EDC, PerCP), PE-Cy5 is a superior fluorochrome for third color analysis because of its high emission intensity and broad spectrum. Be sure to also look up the excitation and emission spectra for your dye of choice. PE/Dazzle™ 594 can be excited by the blue (488 nm), green (532 nm) or yellow/green lasers (561 nm), and is detected in the PE/Texas Red® channel. The beamsplitter is a dichroic filter that acts as a mirror for the excitation wavelengths and is transparent to all other wavelengths. Because of its broad absorption range, PE-Cy5 It is reported to be a somewhat slowly … Exportable as image or link.
