Superiority

High Sensitivity
O-Phthalaldehyde (OPA) reacts with amino groups in amino acids, peptides, and proteins to form a highly fluorescent product, enabling the detection of target compounds at very low concentrations with exceptional sensitivity.

Excellent Fluorescent Properties
OPA exhibits strong fluorescence emission, especially under UV light, producing a distinct fluorescent signal, making it an ideal reagent for the quantitative analysis of amino acids, peptides, and proteins.

Wide Applicability
OPA is widely used in various analytical techniques such as High-Performance Liquid Chromatography (HPLC), Capillary Electrophoresis (CE), and Thin-Layer Chromatography (TLC) for the quantitative analysis of amino acids, peptides, and proteins.

Easy to Use
When used as a reagent for analysis, OPA typically requires minimal sample preparation. Its reaction directly produces a fluorescent signal, simplifying the experimental process, saving time and costs.

High Specificity
OPA reacts specifically with free amino groups in amino acids, providing high specificity in complex biological samples, ensuring accurate identification and analysis of target molecules while minimizing background interference.

Good Stability
Under appropriate storage conditions, OPA demonstrates excellent chemical stability, ensuring long-lasting effectiveness and reliability for extended use.
