Description
Introduction
SB-SCG-W3000 is an imaging device that utilizes chemiluminescence technology and is equipped with a high-sensitivity cooled camera with 9 million pixels. It enables fast, accurate, and high-throughput detection and imaging of samples, and is widely used in fields such as life sciences, medicine, and environmental protection.
Principle
A Chemiluminescence Imaging System operates on the principle of detecting light emitted during a chemical reaction. Chemiluminescence occurs when a chemical reaction produces an excited state intermediate, which then releases energy in the form of light as it returns to a lower energy state. This light emission is captured by the imaging system, typically consisting of a highly sensitive camera (often a cooled CCD or CMOS sensor) and optical components that guide and focus the light onto the detector.

Software Functions | Real-time Imaging: Real-time presentation of changes in sample signals during exposure process, capturing every detail of the capture |
Overexposed areas can be displayed. | After exposure, each frame image within the exposure time can be generated. Users can select any frame image for the final output by precise retrospective adjustment. |
Time Imaging | For samples with insufficient exposure, users can choose to continue exposure after the exposure ends, allowing the sample to gain additional exposure effect based on the already exposed time. |
Auto Exposure | Intelligent exposure technology quickly determines the optimal exposure time. With time imaging and time accumulation functions, users can obtain the best image result with just one operation. |
Apparatus and Equipment
- Real-time Imaging: Present the changes in sample signals during the exposure process in real-time, capturing every detail of the shot. Overexposed areas will be indicated for samples that are overexposed.
- Time Imaging: After the exposure is completed, every frame image within the exposure time can be generated. Through precise retrospective adjustments, users can select any frame image within that exposure time as the final output.
- Time Accumulation: For samples with insufficient exposure, users can choose to continue the exposure after the exposure ends, allowing the sample to obtain additional exposure effects based on the exposure time already accumulated.
- Automatic Exposure: Intelligent exposure technology can quickly determine the optimal exposure time. With the functions of time imaging and time accumulation, users can obtain the best image results with just one operation.
Protocol
System Start-Up and Sample Loading
Begin by connecting the power cord and activating the power switch located at the back of the instrument. This will initiate the startup of the industrial computer, which will automatically load the chemiluminescence imaging software. Once the software interface appears, open the instrument door and remove the sample tray. Carefully place the prepared sample on the tray, ensuring it lies flat, and return the tray into the instrument’s dark box before closing the door.Software Operation and Image Capture
Upon successful software launch, confirm that all system components are functioning correctly by checking the status bar at the bottom left of the screen. If the system passes the self-check, proceed to the preview and capture page by selecting the central icon. On this page, configure the storage location for your experiment results and choose between manual or automatic exposure modes. Adjust exposure settings as needed and start the preview. Once satisfied with the setup, click the capture button to begin the imaging process. After capture, review the images, make any necessary adjustments, and save the final results.
Experimental Options and versatility
Applications
Chemiluminescence Imaging Systems are widely used in various scientific applications due to their high sensitivity and ability to localize and quantify light emission at very low levels. Here are the primary applications based on the scientific articles provided:
Biological Imaging:
- In Vitro Assays: Chemiluminescence imaging is used for quantitative assays in microtiter plates, microarrays, and miniaturized analytical devices. It enables the simultaneous analysis of multiple analytes in a sample, making it suitable for high-throughput screening (HTS) in pharmaceutical and clinical research Roda et al., 2005
- In Vivo Imaging: These systems are essential for imaging biological processes in live animals, allowing researchers to track the localization and dynamics of specific molecules or cells over time. This is particularly useful in studying disease progression, drug delivery, and gene expression Roda et al., 2005
Immunohistochemistry and In Situ Hybridization:
- Chemiluminescence imaging is employed in immunohistochemistry and in situ hybridization to localize and quantify specific proteins, antigens, or gene sequences in tissue samples. The high sensitivity of these systems makes them ideal for detecting low-abundance targets
Environmental and Pharmaceutical Analysis:
- The technology is used in environmental monitoring, such as detecting pollutants like mercury in water samples using luminescent bacterial biosensors. In pharmaceutical applications, chemiluminescence imaging facilitates drug discovery by enabling the rapid screening of potential drug candidates. Roda et al., 2005
Whole-Organ and Whole-Body Imaging:
- In preclinical research, chemiluminescence imaging is applied to visualize whole organs or entire organisms. This application is crucial for evaluating the distribution and effects of drugs, as well as for understanding complex biological systems in real time Roda et al., 2005
These applications highlight the versatility and importance of Chemiluminescence Imaging Systems in advancing scientific research across multiple disciplines.
