| Rhodamine, Dihydro 123, Dihydrochloride Salt (Dihydrorhodamine) | Dihydrorhodamine 123 dihydrochloride is the HCl salt form of dihydrorhodamine 123 and is functionally equivalent to the latter. However, dihydrorhodamine 123 dihydrochloride is more water soluble and more stable to air oxidation than dihydrorhodamine 123. Thus, dihydrorhodamine 123 dihydrochloride is easier to use and can be stored longer than dihydrorhodamine 123.Dihydrorhodamine 123 (DHR 123) is a cell-permeable fluorogenic probe that is useful for the detection of reactive oxygen species (ROS) such as peroxide and peroxynitrite. It is not fluorescent until oxidized by ROS to the highly fluorescent product Rhodamine 123. Neither NO, superoxide, nor hydrogen peroxide alone appear to oxidize DHR, rather, these ROS are thought to combine with other cellular components such as cytochrome c oxidase or Fe2+ in order to oxidize DHR 123 to its fluorescent derivative Rhodamine 123. Formation of Rhodamine 123 can be monitored by fluorescence spectroscopy using excitation and emission wavelengths of 500 and 536nm, respectively, or by absorbance spectroscopy at 500 nm (ε = 78,800 M-1cm-1).

| Riboflavin-5-Phosphate Disodium Salt (Flavin mononucleotide, FMN) | Flavin mononucleotide (FMN), or riboflavin-5?-phosphate, is a biomolecule produced from riboflavin (vitamin B2) by the enzyme riboflavin kinase and functions as prosthetic group of various oxidoreductases including NADH dehydrogenase as well as cofactor in biological blue-light photo receptors. During the catalytic cycle, a reversible interconversion of the oxidized (FMN), semiquinone (FMNH ) and reduced (FMNH2) forms occurs in the various oxidoreductases. FMN is a stronger oxidizing agent than NAD and is particularly useful because it can take part in both one- and two-electron transfers. In its role as blue-light photo receptor, (oxidized) FMN stands out from the 'conventional' photo receptors as the signaling state and not an E/Z isomerization. Group: Biochemicals.
