설명

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.
