Chemiluminescence gel imaging system is an analytical instrument that plays a key role in biomedical research, molecular biology experiments and related fields, providing researchers with accurate and sensitive detection means, and promoting the progress of life science research.

The core principle of this system revolves around chemiluminescence. Chemiluminescence refers to the phenomenon in which certain substances absorb the energy released during a chemical reaction and are in an excited state. When they return to the ground state from the excited state, they release energy in the form of light. In the chemiluminescent gel imaging system, it usually involves the specific reaction between the specific luminescent substrate and the target molecule. For example, when detecting proteins, a series of immune reactions are used to bind luminescent substrates to target proteins, triggering chemiluminescence reactions. This luminescent reaction has high specificity and sensitivity, and can accurately indicate the presence and distribution of target molecules.

From the perspective of system composition, it mainly includes several key parts. Luminescent gel has been specially designed and prepared to produce bright luminous effects under specific chemical reaction or physical excitation conditions. Its internal structure is uniform and stable, providing a suitable reaction environment for the biomolecules to be detected, ensuring that the luminescent reaction can proceed uniformly.

The excitation source plays a crucial role in triggering luminescent reactions in the system. Common excitation sources include lasers or electron beams. The laser can generate a high energy, monochromatic laser beam, accurately irradiate on the luminous gel, and stimulate the luminous substances in the gel to generate light signals. Electron beams, with their high energy and controllability, provide the possibility to achieve specific excitation requirements. The use of these excitation sources can be flexibly selected and adjusted according to different experimental purposes and sample characteristics to achieve excitation effects.

The detector is responsible for collecting and analyzing the weak light signal generated by the luminescent gel. Modern chemiluminescent gel imaging systems usually use highly sensitive charge coupled devices (CCD) as detectors. CCD has photoelectric conversion performance, which can quickly and accurately convert received optical signals into electrical signals and transmit them to subsequent processing units.
