Aplicación

Useful for investigators requiring an alternate sulfhydryl moiety. Requires addition of desired sulfhydryl compound for measuring amines. Requires addition of amine to measure sulfhydryls.
Phthaldialdehyde Reagent has been used for the derivatization plasma samples prior to high performance liquid chromatography.
Precolumn derivatization reagent for primary amines and amino acids. The fluorescent derivative can be detected by reverse-phase HPLC. The reaction requires OPA, primary amine and a sulfhydryl. In the presence of excess sulfhydryl, amines can be quantitated. In the presence of excess amine, sulfhydryls can be quantitated.
