Confocal laser scanning microscopy

We can better understand structure of cells in fluorescent microscopy by images with high resolution. In confocal laser scanning microscopy we can find out even more. This means that we can view visual sections of tiny structures that would be difficult to physically section and construct 3-D structures from the obtained images. For example, different cells are incubated by different florescent calcium indicator dyes (Fura-2, Flo-3 and Fluo-8) for making visible intracellular free Ca2+. We can also measure the florescent dye concentration as indicator of intracellular free Ca2+ concentration. Basic components of confocal laser scanning microscopy are laser, beam splitter, scanner, objective lens, Z-control, pinhole and photomultiplier tube. In our center, we have modern confocal laser scanning microscopy (Zeiss, LSM800) and we will analyze our neuronal cell samples in the microscope.
