Substrats fluorogènes

6-Chloro-7-hydroxy-4-(trifluoromethyl)coumarin is a fungicide that inhibits the growth of fungi by interfering with their DNA synthesis. It does this by inhibiting the activity of two enzymes: the fungal enzyme oxime and the enzyme cinerea, which is found in many fungi. 6-Chloro-7-hydroxy-4-(trifluoromethyl)coumarin has been shown to be effective against Alternaria and Botrytis cinerea. The compound also has an antifungal effect against other types of fungi, such as Penicillium roqueforti, when used in combination with a solvent such as ether.

2-Dodecylresorufin is a fluorescent probe that reacts with the hydroxyl radicals in the cell, which are generated by the enzyme superoxide dismutase. 2-Dodecylresorufin can be used to measure reactive oxygen species (ROS) and ROS-induced cellular damage. It is also used to study oxidative stress in vitro. The chemical structure of 2-dodecylresorufin contains a linker arm that provides a reversible linkage to the cell surface, allowing for extracellular measurements of reactive oxygen species (ROS). This compound has been shown to have high reactivity, making it useful for studying population dynamics and fluorescent techniques.

4-Methylumbelliferyl 4-deoxy-b-D-chitobiose peracetate is a chromogenic substrate used for the detection of β-galactosidase activity. It is an analog of 4-methylumbelliferone that can be hydrolyzed by β-galactosidase to produce fluorescence. This product is supplied as a white crystalline solid and can be stored at room temperature. This substrate has been shown to work well in culture media, food testing, and environmental testing.

D-Alanine 7-amido-4-methylcoumarin free base is a chromogenic substrate that is used in diagnostic testing. It is used to identify the presence of beta-lactamase, which catalyzes the hydrolysis of penicillin and cephalosporin antibiotics, by turning the substrate into a bright blue color. D-Alanine 7-amido-4-methylcoumarin free base can also be used as a fluorescent substrate for bioluminescence or chemiluminescence reactions. This product is high quality and has CAS number 201847-51-0.

Maltotetraose 2-aminobenzamide is a chemiluminescent substrate that emits light in the presence of certain oxidizing agents. It provides high quality and environmental testing, as well as staining and ligand capability. Maltotetraose 2-aminobenzamide is used in diagnostics to identify bacteria and other microorganisms. Maltotetraose 2-aminobenzamide can be used for the detection of bacterial colonies on agar plates using a fluorogenic substrate, or for the detection of fungi using a chromogenic substrate. Maltotetraose 2-aminobenzamide is also used as an enzyme substrate in food testing or conjugate with enzymes for bioluminescence.

4-Methylumbelliferyl-b-D-xylotrioside is a fluorogenic substrate that reacts with an enzyme in the presence of oxygen to produce light. It is used in diagnostic applications, such as detecting the presence of a specific enzyme or protein. 4-Methylumbelliferyl-b-D-xylotrioside can also be used as a chromogenic substrate for the detection of DNA and RNA. This compound can be conjugated with other molecules for use in immunoassays and other diagnostic applications. 4-Methylumbelliferyl-b-D-xylotrioside has been shown to bind to bacterial cells and activate them, which leads to the production of light through bioluminescence.

4-Trifluoromethylumbelliferyl a-D-N-acetylneuraminic acid is a fluorescent chemiluminescent substrate that is used in the detection of beta-galactosidase activity. Beta-galactosidase catalyzes the hydrolysis of 4-trifluoromethylumbelliferyl a-D-N-acetylneuraminic acid to form 4-trifluoromethylumbelliferone and D-galactose, which emits light at approximately 480 nm. This reaction can be detected by fluorescence spectrophotometry using a fluorometer or photometer. 4TFUNA is not toxic, does not inhibit enzymes, and has been tested for toxicity and mutagenicity using bacteria and mammalian cells.
