TMB dihydrochloride
Based on 8 publication(s) in Google Scholar
TMB dihydrochloride is the dihydrochloride form of TMB (HY-15930). TMB dihydrochloride is a non-toxic, non-mutagenic, colorless dye that is also used as a chromogenic agent in enzyme detection systems based on horseradish peroxidase (HRP). TMB dihydrochloride can function as a photoacoustic probe for reactive oxygen and nitrogen species (ROS/RNS), reacting with hypochlorite, hydrogen peroxide, singlet oxygen, and nitrogen dioxide to produce blue oxidation products. TMB dihydrochloride can detect the singlet oxygen produced by the outer membrane of Escherichia coli ATCC 25922.

Biologische Aktivität
TMB dihydrochloride can tightly bind to Escherichia coli ATCC 25922 cells instead of being internalized to detect singlet oxygen produced by the outer membrane[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
