Pacific blue fluorophore
Dec 19, 2016 · We report a new method to quantify the affinity of small molecules for proteins. This method is based on Förster resonance energy transfer (FRET) between endogenous tryptophan (Trp) residues and the coumarin-derived fluorophore Pacific Blue (PB). Tryptophan residues are frequently found in proteins near ligand-binding sites, making this approach potentially applicable to a wide range of ... Super Bright 436 Dye. Invitrogen eBioscience Super Bright 436 dye is a polymer-based fluorophore excited by the violet laser (405 nm) that emits signal at 436 nm with high efficacy.

For example, Alexa Fluor ® 488, PE, PerCP-Cy5.5, and PE-Cy7 are excitable with a blue laser (488 nm). However, they will produce green, yellow, purple, and infrared emissions (Figure 4).1. View Spectra. Normalized emission curves are plotted into each channel off the ultraviolet, violet, blue, yellow/green, and red lasers of Cytek™ Aurora flow cytometers. You can uncheck and remove lasers as necessary to better match your instrument. To view spectra, simply select a fluorophore from one of the dropdowns and then check or ...
An example is the blue fluorophore Pacific Blue, which is isosteric to 7-hydroxycoumarin, and yet not recognized by the latter’s ligase (W37V LplA) or any tryptophan 37 point mutant.

Hypoxyprobe Pacific Blue Kit (100 mg pimonidazole HCl plus 1 unit of Rat IgG1 monoclonal antibody conjugated to Pacific Blue fluorophore (HP-Pacific Blue)) Item# hp15-100kit $459.00Using Pacific Blue and Pacific Orange dyes simultaneously allows you to excite both dyes at the same wavelength while their emissions are differentially distinguished. Pacific Orange and Pacific Blue antibody labeling kits allow the labeling of small amounts of antibody with a violet light-excitable dye (up to 100 µg of antibody per reaction). Pacific Blue, or systemically called 3-carboxy-6,8-difluoro-7-hydroxycoumarin, is a fluorophore used in cell biology. Its maximum excitation wavelength is 401 nm and its maximum emission wavelength is 452 nm. Even at a pH of about 7, its fluorescence is still very high. Pacific Blue is a member of the Pacific Dye Group.
We selected 7-hydroxycoumarin as our fluorophore for this study because its excitation and emission wavelengths are suitable for live-cell imaging (excitation 387–405 nm; emission 448 nm) , it is brighter than Enhanced Blue Fluorescent Protein (EBFP) [ε = 36,700 M-1 cm-1 and QY 0.7 for the anionic form , compared to ε = 31,500 M-1 cm-1 and ...Search life-sciences literature (Over 39 million articles, preprints and more)
