애플리케이션
Phthaldialdehyde has been used:
- to detect Arg through spectrophotometry using end-point fluorescent sensitive detection
- as a reagent stream with the sample to produce a fluorescent product for determining ammonia in seawater
- in the o-phthaldialdehyde spectrophotometric assay (OPA test) to determine the proteolytic activity (PA)of the strains and the commercial cultures
생화학적/생리학적 작용
o-Phthaldialdehyde (OPA) can form fluorescent derivatives while reacting with amino acids.
Phthaldialdehyde can be used for the pre-column derivatization of amino acids for high-performance liquid chromatography (HPLC) separation. It may also be used for flow cytometric measurements of protein thiol groups.

Sphingolipid ceramide N-deacylase (SCDase) catalyzes reversible reactions in which the amide linkage in glycosphingolipids is hydrolyzed or synthesized. While SCDases show great value for the enzymatic synthesis of glycosphingolipids, they are relatively poorly characterized enzymes. In this work, the enzymatic

An overview is presented of HPLC methods currently in use to determine amino acids as their o-phthaldialdyde derivatives in the presence of various SH-group-containing additives. Crucial points that proved to influence the stability of the amino acid OPA derivatives have

This study reports a selective and sensitive method for fluorescent detection of total, protein-bound, free, and free oxidized homocysteine (HCys) using tris(2-carboxyethyl)phosphine (TCEP) as a reducing agent, fluorosurfactant-capped gold nanoparticles (FSN-AuNP) as a preconcentrating probe, and o-phthaldialdehyde (OPA) as a
