The cell environment imaging system can capture high-resolution images, clearly displaying the subtle structure and dynamic processes of cells. This is of great significance for studying the internal mechanisms of cells, the laws of disease occurrence and development, and the effects of drug action. The detailed and accurate image data provided by the system enables researchers to observe and compare at different time points and conditions, ensuring the consistency and reliability of the experiment. In addition, these data can also be used for statistical analysis, revealing potential biological laws and mechanisms, and providing strong support for scientific research.
It has wide application value in multiple fields such as drug development, cancer research, and developmental biology. It can help researchers gain a deeper understanding of the interaction between cells and the microenvironment, explore the mechanisms of disease occurrence, evaluate drug efficacy, accelerate the process of new drug development, and promote progress in the field of life sciences. The automation control function of the system reduces the need for manual intervention, lowers operational difficulty and error rate. At the same time, efficient data processing and analysis capabilities have greatly improved research efficiency, enabling researchers to obtain valuable research results more quickly.
Measurement steps of cell environment imaging system:
1. Experimental design: When designing a live cell imaging experimental plan, various factors need to be comprehensively considered, such as the cellular processes to be observed and the labeling methods used. Because live cell imaging has many advantages, including the ability to observe the occurrence of dynamic cellular processes, use multi-color detection to simultaneously study multiple aspects, study the structure in the native environment of cells to obtain more realistic results, track biomolecules and structures over time, and observe intercellular interactions. However, it is also necessary to pay attention to some issues, such as the need for specific low toxicity methods to label research targets. As live cells are not permeable to certain large detection molecules, it is difficult to maintain focus on moving targets. It is also necessary to consider whether the technology used is harmful to the cells and ensure that the cells are in a natural physiological state.
2. Cell culture: Maintaining or cultivating cells under optimal conditions is crucial. The selection of culture medium is particularly crucial for experiments involving delayed imaging and prolonged exposure to the surrounding environment. To ensure the health of cells and keep them in a suitable environment as close as possible to physiological temperature, pH value, oxygen level, and other conditions, in order to obtain reliable experimental results.
3. Cell labeling: Targeted labeling of cell structure, function, and target proteins using specific dyes and fluorescent labeling reagents. Suitable fluorescent dyes should be selected, such as specific targeted fluorescent proteins or small membrane permeability reagents. If multiple structures and processes need to be detected simultaneously, other fluorescent dyes can be used in combination, but Fluorescence SpectraViewer should be used to check the excitation and emission spectra to minimize spectral overlap between different dyes. Meanwhile, excessive use of fluorescent labeling should be avoided to prevent issues such as non-specific staining, background signal enhancement, physiological artifacts, structural perturbations, cytotoxicity, and severe spectral overlap.
4. Signal optimization: Strive to reduce background interference and maintain the photostability of fluorescence signals. Reagents that can reduce extracellular fluorescence and enhance the photostability of fluorescent dyes can be used to improve the signal-to-noise ratio. Selecting background inhibitors suitable for live cells can help reduce extracellular background fluorescence without the need for additional cleaning steps; Samples can also be treated with live cell anti quenching reagents to prevent signal loss caused by multiple or prolonged exposures.
5. Imaging observation: For live cell imaging of dynamic processes, long-term observation is required. During this process, it is necessary to control the lighting and detection conditions reasonably to ensure the acquisition of high-quality image data.
6. Power on operation: First turn on the cell culture system controller switch, bright field switch, mercury lamp switch, and microscope switch; Next, turn on the carbon dioxide switch to maintain a stable carbon dioxide pressure below 0.1Mpa; Then add an appropriate amount of high-pressure water to the cell culture system and place the cells inside; Afterwards, open the imaging system control software and allow the CCD to pre cool; Find a suitable field of view under the microscope, set relevant parameters, and perform live cell imaging.
7. Shutdown operation: First, close the imaging system control software; Then turn off the switches of carbon dioxide, bright field, mercury lamp, and cultivation system controller in sequence; Then turn off the microscope; Then turn off all power sources; Remove the cells and clean the culture system.
