Application

Phthaldialdehyde Reagent has been used for the derivatization plasma samples prior to high performance liquid chromatography.
Useful for investigators requiring an alternate sulfhydryl moiety. Requires addition of desired sulfhydryl compound for measuring amines. Requires addition of amine to measure sulfhydryls.
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.

Liaison

Same as P 0532, but contains no 2-mercaptoethanol.

We investigated the bactericidal effects and cytotoxicity of an ortho-phthalaldehyde product in comparison with those of its predecessor glutaraldehyde products. Bactericidal effects ware examined on Mycobacterium terrae, a standard organism used for investigating the bactericidal effect of high-level disinfectants. Cytotoxicity

Monomethylarginine, asymmetric dimethylarginine and symmetric dimethylarginine were separated on a Wakopak Combi ODS with an acetonitrile-100 mm potassium phosphate buffer (pH 7.0; 1:1, v/v). Dimethylarginines were derived from o-phthalaldehyde for the fluorescence detector and from 6-ferrocenyl-1-hexanethiol for the electrochemical detector. The
