Description générale

Leucoberbelin Blue I is a colorimetric reagent redox dye. It is a water-soluble leuco base also abbreviated as LBB. Upon oxidation, LBB forms a colored complex which is stoichiometrically related to the oxidation state of the reagent.

Application

Leucoberbelin blue I has been used as a quencher in the time-resolved fluorescence QRET technique for receptor-ligand interaction screening. LBB assay is used to indicate the kinetics of Mn (II) oxides formation.
