hydrogen peroxide

Phenol Red (Sulfonphthal) is a pH indicator, red dye, and diagnostic aid for measurement of renal function. It is used also for researches of the gastrointestinal and other systems.

TMB-PS (TMBZ-PS) is a chromogenic reagent for the detection of hydrogen peroxide e.g. in the enzymatic analysis of body fluids.

IR-990, an activatable NIR-II fluorescent probe featuring an acceptor-π-acceptor (A-π-A) structure, enables real-time in vivo detection of hydrogen peroxide (H2O2). It serves as an effective diagnostic tool for drug-induced liver injury (DILI) [1].

NucPE1, a nuclear-localized fluorescent hydrogen peroxide, is specifically localized to cellular nuclei without appended targeting moieties.

TMB(dihydrochloride x.hydrate) is the dihydrochloride salt and hydrate form of TMB. It is a non-toxic and non-mutagenic colorless dye used as a chromogenic agent in horseradish peroxidase-based assay systems. This compound also serves as a photoacoustic probe for reactive oxygen and nitrogen species (ROS RNS), reacting with hypochlorite, hydrogen peroxide, singlet oxygen, and nitrogen dioxide to produce a blue oxidized product. Additionally, TMB(dihydrochloride x.hydrate) can detect singlet oxygen produced by the outer membrane of Escherichia coli ATCC 25922.

APF is an aromatic amino-fluorescein derivative and fluorescent probe for highly reactive radicals. It has low intrinsic fluorescence, however, upon oxidation by hydroxyl radical, hypochlorite ion, and certain peroxidase intermediates, it is converted to the highly fluorescent molecule fluorescein, facilitating the detection of highly reactive biological radicals. APF is not oxidized by nitric oxide (NO), hydrogen peroxide (H2O2), or other oxidants. Fluorescein displays excitation emission maxima of 490 515 nm, respectively.

10-Methyl-9-(phenoxycarbonyl)acridinium fluorosulfonate, a phenyl ester derivative of acridinium esters, serves as a fluorescent dye exhibiting chemiluminescence in neutral conditions and is utilized in the quantification of hydrogen peroxide [1].

Xylene Cyanol FF, an acid triphenylmethane dye, is utilized for histochemical staining of hemoglobin peroxidase and as a tracking dye for DNA sequencing during electrophoresis. Catalyzed by Fe and Al, it accelerates oxidation with hydrogen peroxide and potassium periodate, enabling spectrophotometric determination of Fe and Al in solutions [1] [2].

FBBBE is a derivatized fluorescein compound that is used to detect the production hydrogen peroxide (H2O2) by cells. Intracellular H2O2, but not extracellular H2O2, initiates the conversion of FBBBE to fluorescein, resulting in an increase in intracellular fluorescence (excitation emission maxima: 480 512 nm).
