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.

Manganese (Mn) oxides are among the strongest oxidants and sorbents in the environment, and Mn(II) oxidation to Mn(III/IV) (hydr)oxides includes both abiotic and microbially-mediated processes. While white-rot Basidiomycete fungi oxidize Mn(II) using laccases and manganese peroxidases in association with lignocellulose

In terms of its oxidative strength, the MnO2/Mn2+ couple is one of the strongest in the aquatic environment. The intermediate oxidation state, manganese(III), is stabilized by a range of organic ligands (Mn(III)-L) and some of these complexes are also strong
