I. Advantages of Acridinium Ester Reaction


1.High luminous efficiency and intensity

Acridinium ester compounds can emit intense light signals under specific conditions, with a much higher luminous efficiency than other luminescent labels. This high luminous efficiency endows acridinium ester reaction with high sensitivity in chemiluminescence immunoassay, enabling accurate detection of low-concentration biomolecules.


1.Rapid reaction

Acridinium ester reaction possesses rapid luminescent properties. Once the initiator is added, it can emit intense light signals in a very short time. This rapid reaction speed allows chemiluminescence immunoassay to be completed in a short period, improving analytical efficiency.


2.Low background luminescence and high signal-to-noise ratio

Compared to other luminescent labels, acridinium ester exhibits lower background luminescence during the reaction, leading to a higher signal-to-noise ratio. This means that the difference between the target signal and background noise is more pronounced, improving the accuracy of detection.


3.Easy coupling with proteins

Acridinium ester compounds are easily coupled with proteins, and the coupling does not affect their luminescent properties. This allows acridinium ester to be used as a luminescent label for detecting various biomolecules, such as antibodies and antigens.


II. Disadvantages of Acridinium Ester Reaction


1.Poor photostability

Acridinium ester compounds are prone to photodegradation under prolonged exposure to light, resulting in weakened luminescent effects. Therefore, strict control of light exposure time and intensity is necessary to ensure the accuracy of experiments.


2.Instability in buffers, prone to hydrolysis

Acridinium ester is prone to hydrolysis in specific buffers, reducing its stability. This affects its application in chemiluminescence immunoassay, and thus, appropriate buffer conditions need to be selected during the experiment.


III. Application of Acridinium Ester Reaction in Chemiluminescence Immunoassay


Due to its advantages, acridinium ester reaction has been widely applied in chemiluminescence immunoassay. By labeling antigens or antibodies, acridinium ester can achieve high sensitivity and specificity in detecting target molecules. In the biomedical field, acridinium ester reaction is used for diagnosing various diseases such as infections.


IV. Conclusion


In summary, acridinium ester reaction, as an important method in chemiluminescence immunoassay, possesses both advantages and limitations. In practical applications, we need to fully understand its pros and cons and select appropriate experimental conditions and operating procedures based on specific needs. By continuously optimizing experimental conditions and improving technical level, we can better leverage the advantages of acridinium ester reaction in chemiluminescence immunoassay, providing more accurate and sensitive detection methods for biomedical research and clinical diagnosis.
