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
チオ-ルの蛍光プロ-ブやHPLCで生体チオ-ルのプレカラム標識に用いられます。
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.

Metallothionein (MT) is a low-molecular-weight protein which plays a role in detoxification of heavy metals and protection against oxidative stress. A sensitive and convenient determination method for MT is necessary to clarify its physiological roles. High-performance liquid chromatography (HPLC) with

A sensitive HPLC-fluorescence method for determining total endogenous plasma homocysteine (Hcy), cysteine (Cys) and cysteinylglycine (Cys-Gly) following derivatization with ammonium 7-fluoro 2,1,3-benzoxadiazole-4-sulphonate (SBD-F) is described. Quantitation utilizes an internal standard, 2-mercaptoethylamine. The derivatization procedure has been optimized for concentration of

Analytical methods to measure plasma total homocyst(e)ine (tHcy) concentrations are reviewed. High-pressure liquid chromatography (HPLC) with fluorometric detection is the most widely used method to determine plasma tHcy concentrations. Both monobromobimane and ammonium 7-fluorobenzo-2-oxa-1,3-diazole-4-sulphonate (SBD-F) are popular thiol-specific fluorogenic agents

Pseudomonas sp. 109 produces a unique lipase (LipL) which efficiently catalyzes intramolecular transesterification of omega-hydroxyesters to form macrocyclic lactones. The production of the enzymatically active LipL requires a specific molecular chaperon (LimL protein) together with a low-M(r) lipase-activation-factor (LAF) of
