What is a Spectra Viewer?
Use this spectra viewer to interactively view the excitation and emission spectra for our fluorescent dyes (including Janelia Fluor®, TFAX, Cyanine and BDY dyes). Spectra for other dyes are also included for reference purposes. Note: absorption spectra may be displayed instead of excitation spectra. …
What is BV421?
BD Horizon™ Brilliant Violet™ 421 (BV421) (Exmax 407 nm/Emmax 421 nm) is a polymer-based dye excited by the violet laser and is one of the brightest fluorochromes offered by BD Biosciences. This dye offers improved brightness over Pacific Orange™ and reduced spillover into the FITC channel when compared to AmCyan.
What is FAM fluorophore?
FAM is the most commonly used fluorescent dye attachment for oligonucleotides and is compatible with most fluorescence detection equipment. It becomes protonated and has decreased fluorescence below pH 7; it is typically used in the pH range 7.5–8.5. FAM can be attached to 5′ or 3′ end of oligos.
How do you compensate FACS?
How To Compensate A 4-Color Flow Cytometry Experiment Correctly
- 4 Steps To Compensating A 4-Color Experiment.
- Choose the correct carrier for compensation.
- Step 2: Collect the data and make sure there is a sufficient number of events.
- Calculate compensation correctly.
- Apply the compensation values and inspect the results.
What is a fluorescence excitation spectrum?
A fluorescence excitation spectrum is when the emission wavelength is fixed and the excitation monochromator wavelength is scanned. In this way, the spectrum gives information about the wavelengths at which a sample will absorb so as to emit at the single emission wavelength chosen for observation.
How do Fluorochromes work?
Fluorochromes absorb light energy of a specific wavelength and re-emit it at a longer wavelength. Therefore, the fluorochrome brightness will depend on its ability to absorb light and the efficiency at which the absorbed light is converted into emitted light.
How does a fluorophore work?
Fluorescent molecules, also called fluorophores or simply fluors, respond distinctly to light compared to other molecules. As shown below, a photon of excitation light is absorbed by an electron of a fluorescent particle, which raises the energy level of the electron to an excited state.
What are the spectral characteristics of fluorophores?
Each fluorophore has its own spectral characteristics, with excitation and emission spectra particular to the molecule. Use the spectra viewer to build dye panels suitable for your experiment by plotting individual dye characteristics and instrument set up.
What is the fluorescent spectraviewer?
Fluorescent Spectraviewer 1 Supports flow cytometry, fluorescence microscopy, and western blotting 2 Displays the excitation and emission profiles of the fluorophores available to you, essential when building multicolor panels for flow cytometry 3 Allows full customization: select any fluorophore, laser, and filter combination
How do I add additional fluorophores to the spectraviewer?
The number of Fluorophores added to the SpectraViewer will be displayed by a number located to the left of Fluorophores. (B) Additional fluorophores— continue to select additional fluorophores by using the Add fluorophore at the bottom of the right-hand column.
How do I find the right fluorophore for my application?
Find the right fluorophore for your application using our new interactive, fluorescent spectraviewer with hundreds of fluorophores to choose from. Bio-Rad’s new spectraviewer is the only spectraviewer to allow a multi-laser view and support 3 applications in a single tool.
