Introduction To order Documents Related products Introduction Dihydrorhodamine 6G is the reduced form of rhodamine 6G, which is used as fluorescent mitochondrial dye. It is nonfluorescent, but it readily enters most of the cells and is oxidized by oxidative species or by cellular redox systems to the fluorescent rhodamine 6G that accumulates in mitochondrial membranes.

DHR 123 [Dihydrorhodamine 123]
Introduction To order Documents Related products Introduction Dihydrorhodamine 123 is the reduced form of rhodamine 123, which is a commonly used fluorescent mitochondrial dye. Dihydrorhodamine 123 itself is non-fluorescent, but it readily enters most of the cells and is oxidized by oxidative species or by cellular redox systems to the fluorescent rhodamine 123 that accumulates […]

DHE [Dihydroethidium]
Introduction To order Documents Related products Introduction Dihydroethidium (also called hydroethidium) is the chemically reduced form of the commonly used DNA dye ethidium bromide. The probe is useful to detect oxidative activities in viable cells, including respiratory burst in phagocytes. Dihydroethidium itself has blue fluorescence (Ex/Em: 355/420nm) in cells, while the oxidized form ethidium has […]

Probes for ROS
Introduction To order Related Products Introduction Generation of reactive oxygen species (ROS) at a controlled level is a feature of live cell function. Under conditions of oxidative stress, ROS production is dramatically increased, resulting in damage of membrane lipids, proteins, and nucleic acids. Oxidative damage is associated with aging as well as many diseases. Probes […]

FDG (Fluorescein di-β-D-galactopyranoside)
Introduction To order Documents Introduction Fluorescein di-β-D-galactopyranoside (FDG) is one of the most sensitive substrates for galactosidases. Nonfluorescent FDG is sequentially hydrolyzed by β-galactosidase, first to fluorescein monogalactoside (FMG) and then to highly fluorescent fluorescein. Enzyme-mediated hydorlysis of FDG can be followed by the increase in either absorbance or fluorescence. Specifications Label: fluorescein Ex/Em: […]

Peroxidase Substrate: Amplex Red
Introduction To order Documents Introduction 10-Acetyl-3,7-dihydroxyphenoxazine (Known as Amplex Red™ reagent, Trade Mark of Molecular Probes) is regarded as the best fluorogenic substrate for peroxidase, because it is highly specific and stable. The substrate itself is nearly colorless and nonfluorescent until it is oxidized by H2O2 in the presence of horseradish peroxidase (HRP) to become […]

MQAE
Introduction To order Documents Related products Introduction MQAE is a 6-methoxyquinolinium derivative and is a fluorescent indicator for intracellular Cl–. This dye detects the ion via diffusion-limited collisional quenching. MQAE has greater sensitivity to Cl– and a higher fluorescence quantum yield than SPQ; consequently, it is currently the more widely used of the two indicators. […]
