General description

7-Fluorobenzofurazan-4-sulfonic acid ammonium salt, also known as SBD-F, is a low molecular weight sensitive fluorescent probe. SBD-F reacts with sulfhydryl groups (disulfides do not react with SBD-F and must first be reduced to thiols, such as tributylphosphine) to produce highly fluorescent compounds. The rate of reaction of thiols with SBD-F gradually increases with increasing pH. High fluorescence intensities are observed at pH 2-12. SBD-F has an excitation range between 380-385nm and an emission range between 510-515nm.

Application

Fluorescent probe for thiols and pre-column labeling of biological thiols for HPLC
SBD-F is suitable for the HPLC determination of biological thiols at the picomole level. SBD-F has been used in HPLC methods for measuring total plasma and serum homocysteine levels. It is also suitable to determine metallothionein in a tandem column HPLC method with an isocratic solvent system. SBD-F has been used for determining the position of disulfide linkages of cysteine residues in proteins and for detecting cysteine-containing peptides.
