Substrats fluorescents

1,9-Dimethyl-methylene blue zinc chloride double salt is a fluorescent dye that has been used in the study of hyaluronic acid and mesenchymal stem cells. The compound absorbs light at a wavelength of 580 nm, which is the same as the absorption wavelength for hyaluronic acid and mesenchymal stem cells. 1,9-Dimethyl-methylene blue zinc chloride double salt can be used to measure the amount of these compounds in tissues. This dye also shows sensitivity to artifacts such as hemolysis and lipemia, making it useful for research purposes.

Nonhydrolyzable fluorescent glucose analog used to monitor glucose uptake

Single isomer of 5(6)-ROX. It is a fluorescent dye used in RT-PCR methods as an internal reference to determine fluorescence variation that is not associated with the amplification process (plastic of the wells, small differences in concentration or volume, instrument measurements). It produces a constant fluorescence emission signal during the PCR process that is used to normalise the emission produced by the reporter. The fluorescence signal is compatible with that of most reporters. It is used to label the 5’ end of oligonucleotides as a reporter in the presence of a quencher at the 3’ end (dual labelled probe). During amplification, the dye is cleaved, and the fluorescence increases proportionally with the amount of the specific sequence amplified during the PCR process. The development of the fluorescence signal is therefore specifically related to the amplification of the target sequence. 6-ROX with NHS-activated carboxylic acids reacts with primary amines.

Nucleic Acid Dye Green I is a DNA-staining dye that has found application in various high resolution assays for the detection of microbial or viral contaminant DNA.

9,10-Bis[2-(4-methoxyphenyl)ethynyl]anthracene is a reagent for chemiluminescence research.

Benzo[k]fluoranthene is a polycyclic aromatic hydrocarbon that is used as an optical sensor for transcriptional regulation. It has been shown to activate the transcription factor NF-κB, which induces expression of inflammatory genes in cells. Benzo[k]fluoranthene can be used to measure changes in gene expression and protein levels. The antibody response to benzo[k]fluoranthene was studied using a kinetic data analysis method. Benzo[k]fluoranthene has also been shown to induce genotoxic effects in liver cells and human hepatoma cell line HepG2. This compound also causes light emission when it is excited with light, which can be measured with synchronous fluorescence.

Produces a fluorogenic signal in the presence of peroxidase

Weakly fluorescent blue dye; indicator of mitochondrial activity. The reduction of resazurin has been ascribed to a putative reductase or diaphorase-type enzymes from the mitochondria and cytosol but also it might play a role as an intermediate electron acceptor in the electron transport chain between the final reduction of oxygen and cytochrome oxidase.
