일반 설명

Phthaldialdehyde, also known as o-Phthalaldehyde or OPA, is a pre-column (HPLC) derivatization reagent. OPA reacts with primary amino acids (AA) except cystine to form highly fluorescent adducts. The fluorescence of the derivatives is monitored at excitation and emission wavelengths of 345nm and 455nm, respectively. The HPLC technique efficiently separates the OPA-AA derivatives.

애플리케이션

Phthaldialdehyde or OPA determines amino acids in proteins from animal tissue and food samples. Quantification of amino acids adducts of tyramine and phenylethylamine produced by lactic acid bacteria used OPA as the pre-column derivative reagent for HPLC. Intracellular forms of glutathione (GSH/GSSG) are investigated using o-Phthalaldehyde as the pre-column fluorescent agent.

생화학적/생리학적 작용

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.

Flavonoid bioavailability and bioactivity is associated with interindividual variability, which is partially due to differences in health status. Previously, it was demonstrated that cellular stress, especially mitochondrial stress, increases intracellular quercetin uptake and this is associated with beneficial health effects.

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
