The cyanine dye triS-C4(5) as a cationic uncoupler of oxidative phosphorylation: interaction with mitochondria detected by derivative spectrophotometry.
Derivative spectrophotometry was used to study the interaction of the cationic uncoupler triS-C4(5) with mitochondria. The uncoupling action of this dye is dependent on the presence of Pi in the incubation medium. The second derivative spectrum of the dye changed with the incubation period, becoming similar to the spectrum in chloroform; but, after a time, the spectral pattern reverted to the o...

Cyanine dyes attached to DNA via a rigid linker show useful fluorescence and FRET properties without altering the stability of duplex DNA.
متن کاملInteraction of Anionic Azo Dye and TTAB - Cationic Surfactant
A interação entre três corantes aniônicos azo: C.I. Vermelho Ácido 14 (AR14), C.I. Vermelho Ácido 1 (AR1), C.I. Laranja Ácido 7 (AO7) e um surfactante catiônico, o brometo de tetradeciltrimetilamônio (TTAB), foi investigada por meio da técnica de eletrodo seletivo para surfactante. O eletrodo seletivo para TTAB foi construído e usado para determinar a concentração de monômeros TTAB e, também, d...
متن کاملTime-resolved excited state dynamics of a cyanine dye
X Ž . The photophysics and isomerization dynamics in the excited state of a cyanine dye, 3,3 -di 3-sulfopropyl -thiacyanine triethylaminium salt was investigated. Using the femotosecond time-resolved fluorescence up-conversion technique, wavelength-dependent fluorescence dynamics was observed and the theoretical prediction of the dual fluorescence behavior was vindicated. The results were expla...
متن کاملCyanine dye dUTP analogs for enzymatic labeling of DNA probes.
Fluorescence in situ hybridization (FISH) has become and indispensable tool in a variety of areas of research and clinical diagnostics. Many applications demand an approach for simultaneous detection of multiple target sequences that is rapid and simple, yet sensitive. In this work, we describe the synthesis of two new cyanine dye-labeled dUTP analogs, Cy3-dUTP and Cy5-dUTP. They are efficient ...
