The ground state of a cyanine dye, though often pictured with a quaternary and tertiary nitrogen, exists as a hybridized structure between the two extremes. Fluorescein and Cy3 are an important donor−acceptor pair of fluorophores; the characteristic Förster length for this pair on DNA is 56 Å, so the pair can be used to study relatively long distances. Cy®stands for 'cyanine', and the first digit identifies the number of carbon atoms between the indolenine groups. 8 The distinguishing feature of cyanine dyes is a conjugated carbon chain with nitrogen atoms on either end. 1 Product Result | Match Criteria: Product Name, Description Synonyms. Prices listed above are for 5' modification. Internal and 3' incurs additional charges and are post synthesis conjugation to a primary amino group thus an additional modification with an amino group is required. A C6 or C12 amino group can be placed at the 5' or for the 3' end a C3 or C7 amino and for internal positions an amino modified base is used, e.g Amino dT C6.

MISSION ® siRNA Fluorescent Universal Negative Control #1, Cyanine 3. Squarylium cyanine dyes are 1,3-disubstituted compounds resulting from the condensation of one equivalent of squaric acid (3,4-dihydroxy-1,2-dioxocyclobut-3-ene) with two molar equivalents of electron donating aromatic (like aniline, N,N-dimethylaniline) or heterocyclic (like 2-methyl-indolenines, 2-methyl-benzathiazole or 2-methyl-benzoselenazoles) methylene bases, Fig. 1 B).This … This Double Labeling of Oligonucleotide Probes for Fluorescence In Situ Hybridization (DOPE-FISH 0 strategy may provide an effective solution to the problem of low signal intensity, which is commonly observed when using corresponding singly-labeled FISH probes for microbe identification. Call 800-990-8053 or send a request to info@aatbio.com for bulk quote. Accordingly, cyanine dyes show the light absorption of a charge transfer through the central polymethine structure. The conjugate solution can be stored at 4 °C for two months without significant change when stored in the presence of The N-heterocycle on the one side is a cationic ammonium with an electron-withdrawing effect, and the other N-heterocycle is a tertiary amine with an electron-donating effect. The R groups in the diagram represent \(H\), \(CH_3\), \(CH_3CH_2\), or many other moieties including ring structures. The cyanine dyes are brighter in the non-polar environment than in an aqueous medium, resulting in less acquisition time in the confocal microscope than that required for DyLight and Alexa Fluor® dyes (Figure 1), even though those dyes are brighter in aqueous mounting media. C29H35IN2. Using the kit components, the customer converts the carboxylic acid (not supplied) to an activated N -hydroxysuccinimide (NHS) ester, followed by reaction with an equivalent amount of the amine cyanine 3 dye. Mills and Wishart (1920) cite Spalteholz as having discovered cyanine dyes in 1883 independently of Hoogewerff and van Dorp also in 1883 and it is clear from Mills and Wishart's article that the molecular structure of cyanine dyes had become a subject of intense interest by 1920.
