At NINGBO INNO PHARMCHEM CO.,LTD., we understand the critical need for reliable reagents in scientific research. O-Phthalaldehyde (OPA) is one such indispensable compound, celebrated for its exceptional performance in biochemical assays, particularly for the sensitive detection and quantification of amino acids. Its unique chemical properties enable researchers to achieve high levels of precision and sensitivity, which are paramount in various fields, from molecular biology to clinical diagnostics.

The utility of OPA in amino acid analysis stems from its specific reactivity with primary amines. In the presence of a thiol reagent, such as 2-mercaptoethanol or N-acetyl-L-cysteine, OPA reacts with primary amino groups to form highly fluorescent isoindole derivatives. This reaction is rapid and efficient, allowing for the precise measurement of amino acids, peptides, and proteins. The resulting fluorescence is typically measured at specific wavelengths, providing a quantitative output that can be correlated to the concentration of the analyte.

The sensitivity of the OPA assay is a major advantage. It allows for the detection of amino acids at very low concentrations, often in the picomole range. This is crucial in biological samples where amino acid levels can be minute. For instance, in the study of protein hydrolysis, monitoring individual amino acid profiles, or in metabolic research, the ability to accurately measure trace amounts is vital for obtaining meaningful results.

The application of OPA in biochemical assays is widespread. It is commonly used in conjunction with chromatographic techniques, such as High-Performance Liquid Chromatography (HPLC), to separate and quantify individual amino acids in complex mixtures. It is also employed in simpler spectrophotometric methods for rapid screening. The reagent's stability in solution under appropriate conditions further enhances its practicality for routine laboratory use.

Beyond amino acid analysis, the precise chemical interaction of OPA with primary amines also finds applications in quantifying amines in various biological fluids and tissues. This broad utility solidifies OPA's position as a cornerstone reagent for researchers investigating metabolic pathways, enzyme activity, and cellular signaling.
