Analysis of the application advantages of acridine ester in cytokine detection

In the fields of biomedical research and clinical diagnosis, precise detection of cytokines is of great significance for studying disease mechanisms, monitoring disease conditions, and evaluating treatment efficacy. However, the natural content of cytokines in the body is extremely low, and conventional detection methods often fail to meet the needs of precise analysis. This situation has driven continuous innovation in detection technology. Among them, the acridine ester chemiluminescence method has shown significant advantages in the field of cytokine detection due to its unique technical characteristics, providing an effective solution to the problem of detecting low concentration target substances.

1, Technical challenges and requirements for cytokine detection

Cytokines, as important signaling molecules in the body, participate in regulating various physiological processes such as immune response and inflammatory response. Their concentration changes are closely related to the occurrence and development of diseases such as infections, autoimmune diseases, and tumors. However, the concentration of such substances in body fluids is usually in the range of pg/mL to ng/mL, and traditional detection methods have significant limitations in sensitivity. At the same time, clinical testing has high requirements for the accuracy, stability, and detection efficiency of results. It is necessary to avoid misjudgment caused by cross reactions and adapt to rapid analysis of batch samples. These requirements set strict standards for the selection of detection techniques.

2, Comparison of mainstream chemiluminescence detection technologies

Due to its high sensitivity and automated operation advantages, chemiluminescence has become the mainstream technology direction for cytokine detection. The commonly used chemiluminescence techniques currently include three categories: enzymatic chemiluminescence (represented by luminol and alkaline phosphatase substrates), acridine ester direct chemiluminescence, and electrochemiluminescence (represented by tris (pyridinium) ruthenium).

From a technical perspective, enzymatic chemiluminescence relies on the catalytic action of enzymes to generate luminescent signals, and the reaction process is greatly influenced by enzyme activity; Although electrochemiluminescence has stable detection performance, it requires high hardware configuration of the detection equipment, and the equipment procurement and maintenance costs are relatively expensive. In contrast, acridine ester direct chemiluminescence does not require the involvement of enzymes and can directly generate luminescent signals through specific chemical reactions. This not only simplifies the reaction process, but also reduces the interference of enzyme activity fluctuations on detection results. At the same time, it has more advantages in equipment cost control and is easier to promote and apply in conventional laboratories.

3, Improvement of traditional enzyme-linked immunosorbent assay by acridine ester method

Before the widespread application of acridine ester chemiluminescence technology, enzyme-linked immunosorbent assay was a commonly used method for cytokine detection, but this technology has significant limitations. On the one hand, the horseradish peroxidase or alkaline phosphatase markers used in enzyme-linked immunosorbent assay are prone to deactivation during storage and use, which affects the stability of detection; On the other hand, its chromogenic substrate is sensitive to light and prone to decomposition, further increasing the uncertainty of the detection results. In addition, the sensitivity of enzyme-linked immunosorbent assay is relatively low, making it difficult to accurately detect low concentrations of cytokines, and it is prone to cross reactivity with structurally similar compounds, which may lead to inaccurate detection results and affect clinical judgment.

The acridine ester chemiluminescence method effectively improves the above-mentioned problems. Its characteristic of not requiring enzyme catalysis avoids interference caused by changes in enzyme activity; The luminescence signal is stable and not affected by substrate photodecomposition, resulting in stronger detection repeatability; At the same time, higher sensitivity enables it to accurately capture changes in the concentration of low concentration cytokines, significantly improving its specific recognition ability for structurally similar compounds, effectively reducing the probability of cross reactions, and significantly improving the accuracy and reliability of detection results.

4, The application value of acridine ester method in cytokine detection

Overall, the acridine ester chemiluminescence method combines high sensitivity and specificity in cytokine detection with the advantages of simple operation and controllable equipment cost, which can meet the precise detection needs of cytokines in clinical diagnosis and scientific research experiments. With the continuous optimization of technology, the acridine ester method will further improve in detection speed, sample compatibility, and other aspects, providing stronger technical support for the research and diagnosis of cytokine related diseases. Its application prospects in the field of biomedical detection will be even broader.
