The fully automated enzyme immunoassay system is an automated device used for high-throughput biological sample detection. It combines enzyme-linked immunosorbent assay (ELISA) technology with automated processing systems and is widely used in clinical diagnosis, medical research, food safety, environmental monitoring, and other fields. The core advantages of this system are high efficiency, high precision, and easy operation, which can automate the entire process from sample addition, reaction, washing to final detection result output.
1. Working principle of fully automatic enzyme immunoassay system
The working principle of the fully automated enzyme immunoassay system is based on enzyme-linked immunosorbent assay (ELISA) technology, which is an experimental method for quantitatively or qualitatively analyzing the content of target molecules (such as proteins, antibodies, hormones, etc.) in a sample through specific reactions between antigens and antibodies. The specific process includes the following steps:
1. Sample addition: The sample and reagent will be automatically added to the preset microplate, and the surface of the microplate is usually coated with specific antibodies or antigens.
2. Binding reaction: The test substance (antigen or antibody) undergoes a specific binding reaction with the corresponding antibody or antigen on the surface of the microplate.
3. Washing: Remove unbound components through an automated washing system to reduce background interference and ensure the accuracy of detection results.
4. Enzyme labeling reaction: Enzyme labeled secondary antibodies (such as HRP, AP, etc.) are added to form enzyme labeled complexes by binding the antibodies to the target substance.
5. Substrate reaction: Adding substrate solution, enzyme catalyzes substrate reaction, producing measurable signals (such as color change, fluorescence, chemiluminescence, etc.).
6. Detection and result output: The automation system detects the reaction results through devices such as photometers and fluorescence meters, and generates quantitative or qualitative reports.
