This derivative contains pure 5-isomer of ROX. Since the ROX Reference Dye does not interfere with the qPCR reaction and has an easily discernable red emission spectrum, it provides an excellent baseline in multiplex qPCR assays. Thanks Rasmus for the link to the brochure, but what i'm trying to find is the actual excitation and emission spectra of those dyes.

Fluorescence spectra of Rox and Cy5. (Figure S3) 5. Excitation Emission PE-Cy 5® Laser line (488) Tandem (PE-Cy5 ® ) Excitation and Emission Spectral Profiles Energy Level Diagrams Fluorochromes have unique and characteristic spectra for absorption (excitation) and emission. Therefore it is necessary to use the more labile "ultramild" dmf-protected dG monomer rather than the more common isobutyryl dG phosphoramidite in the synthesis of Cyanine dye-labelled oligonucleotides (see Deprotection of heterocyclic bases). School of Chemistry Spectral Characteristics Wavelength (nm) Excitation 400 450 500 550 600 Emission 1. Right: pH dependence of MeU emission spectra. This is coupled to the 5-position of 5′-DMT-5-iodo-2′-deoxyuridine in a Sonogashira reaction using tetrakistriphenylphosphine palladium (0), copper iodide and triethylamine in DMF.

United Kingdom (a) The PL emission spectra of 50 μg mL −1 Cd-MOF/Tb 3+ before and after ultrasonic exfoliation under excitation of 294 nm UV light, the inset compares the emission intensities at 546 nm of Cd-MOF/Tb 3+ before and after ultrasonic exfoliation; (b) The emission spectra of Cd-MOF/Tb 3+ nanosheets colloidal suspension in aqueous systems after placing for various durations and the … However, this would destabilize any duplex formed between the oligonucleotide and a complementary strand, as the monomers do not possess a heterocyclic base, and therefore have no means of base pairing. The fluorescein and linker moieties do not affect the ability of the labelled thymine to form base pairs. Figure 7 | Fluorescein phosphoramidite monomer, and chlorinated derivativesStructures of the fluorescein (FAM) phosphoramidite monomer, and its chlorinated derivatives HEX, TET and ROX. ROX (carboxy-X-rhodamine) is spectrally similar to Alexa Fluor 568, TF4 (Tide Fluor 4), iFluor 594, and Texas Red. ROX passive reference dye is a stabilized conjugate of carboxy-X-rhodamine in water. Excitation and emission of energy in the donor molecule conforms to the model shown in Figure 1. For direct comparison, laser powers were adjusted to equivalent levels, which were ≈1.0 mW. The excitation and emission spectra of the fluorescent dyes are shown in FIGS. Now let’s look at the light that is emitted by the fluorophore molecules when they are excited at the optimal excitation wavelength. The excitation and emission wavelength of the Yakima Yellow dye is 525 nm and 549 nm, respectively, and so it emits in the yellow-orange part of the visible spectrum. Figure 1 Fluorescence excitation and emission spectra of the oxidized CellROX® Oxidative Stress Reagents. Exportable as image or link. Many real-time thermal cyclers require an internal reference dye … A tandem dye consists of a Characterization of EvaGreen Dye and the implication of its physicochemical properties for qPCR applications. For Research Use Only. Storage Conditions: store at -20 °C Short term exposure (up to 1 week cumulative) to ambient temperature possible. The major applications of fluorescent and fluorogenic oligonucle… Some Cyanine dyes are available as phosphoramidites (Figure 8) for addition to the 5′-end of oligonucleotides during solid-phase synthesis. Mao, et al. TAMRA Emission. There is a spectrum of energy changes associated with these emission events. The Spectra of Atto Dyes Atto 390 Spectrum , the fluorescence of Atto 390 can be excited efficiently in the range 360 - 410 nm. Calcofluor White has extremely broad excitation/emission spectra, and as a result almost any filter set with UV or violet/blue excitation wavelengths will generate fluorescence emission which may be detected across a very broad range. CD spectra of I-strand, DNM and C-DNM in pH 5.0 and pH 7.4 solutions. Spectral Properties . Left: pH dependence of MeU excitation spectra.
