company news about Importance of Acridinium Ester NSP-DMAE-NHS in Biochemical Detection

As an important part of modern biomedical research and clinical diagnosis, biochemical detection relies on efficient, sensitive and stable chemiluminescent reagents. Among them, acridinium ester NSP-DMAE-NHS, as a commonly used chemiluminescent marker, plays a vital role in biochemical detection with its unique chemical properties and wide application fields.

1. Structural characteristics and chemiluminescence mechanism
Acridinium ester NSP-DMAE-NHS is a complex composed of an acridinium ester group and a derivative of N-sulfopropyl dimethylaminophenol (DMAE-NHS). The N-sulfopropyl group in its molecular structure gives the compound good water solubility, while the acridinium ester group determines its excellent chemiluminescent properties. This structural characteristic gives acridinium ester NSP-DMAE-NHS a significant advantage in the field of chemiluminescence.
The direct chemiluminescence mechanism of acridinium ester NSP-DMAE-NHS is mainly based on the energy transfer process within its molecule. Under the action of excitation light, the electrons in the acridinium ester DMAE-NHS molecules are excited to the energy level state to form excited state molecules. When these excited state molecules return to the ground state, they release energy and produce chemiluminescence. This luminescence process does not rely on the addition of external catalysts, so it is called direct chemiluminescence.

2. High sensitivity and stability
The acridinium ester NSP-DMAE-NHS has high sensitivity and stability, and can accurately and stably detect the presence and changes of target molecules in complex biological systems. Its excellent fluorescence properties and chemical stability make it an indispensable and important tool in biomedical research.
Under alkaline conditions, the acridinium ester NSP-DMAE-NHS reacts with hydrogen peroxide to produce chemiluminescence. In this process, NHS ester (N-hydroxysuccinimide ester) as an activated carboxylate group can react with the primary amino group in the protein to form a stable amide bond. This step enables the acridinium ester to successfully label proteins, thereby realizing sensitive detection of proteins in chemiluminescence reactions.
