Intracellular distribution of CPT-11 in CPT-11-resistant cells by confocal laser scanning microscopy technology (CAT#: STEM-MIT-0154-LJX)

Laser scanning confocal microscope is a high-tech microscope. It is based on fluorescence microscope imaging and equipped with a laser scanning device, which uses ultraviolet or visible light to excite the fluorescence probe, thereby obtaining fluorescence images of the internal microstructure of cells or tissues.
The laser beam is used as the light source in the laser scanning confocal microscope. The laser beam passes through the illuminating pinhole and is reflected to the objective lens through the spectroscope. The laser beam is focused on the sample, and every point on the focal plane of the specimen is scanned. If there is a fluorescent substance that can be excited in the tissue sample, the fluorescence emitted after excitation is directly reversed back to the spectroscope through the original incident light path, and is first focused when passing through the detection pinhole. The focused light is detected and collected by the photomultiplier tube (PMT), and the signal is sent to the computer, and the image is displayed on the computer monitor after processing.
