Light Microscopy–Fluorescence Services

About the service
Avicenna Research Institute's light-fluorescence microscope laboratory is equipped with both upright and inverted light-fluorescence microscopes, enabling researchers and students to observe and capture images of cell and tissue samples on standard slides or culture media. Since cell and tissue samples are transparent and lack sufficient contrast, the observed image may not reveal distinguishable or reliable details. To address this, various methods have been developed to color cell or tissue components and enhance contrast, thereby displaying sample details. It is important to note that the choice of staining protocol for cells or tissues determines whether the observation should be conducted using the light microscope mode or the fluorescence microscope mode. When chemical-chromogenic methods (cytochemical and histochemical methods) are employed to stain samples, the optical part of these microscopes can be used for capturing photographs. On the other hand, samples stained using fluorochromes and following immunofluorescence protocols require the fluorescence capabilities of the microscope for observation and photography.
1. The Olympus BX51 upright microscope is equipped with a DP71 highly sensitive camera. The Olympus BX51 upright microscope, featuring a DP71 highly sensitive camera, requires samples to be prepared on glass slides for observation and imaging.










    • For samples that have been chemically stained and mounted using Entellan® adhesive, they can be observed and photographed using the optical mode of the microscope. These slides do not necessitate any specific precautions or additional care like fluorescence samples.
    • In the case of fluorescence samples prepared on glass slides, a mounting solution of PBS-Glycerol in a 50/50 ratio is typically used. To prevent the slides from drying out, they should be placed in light-impermeable plastic boxes with a small amount of water at the bottom. These slides can be stored in a cold environment at temperatures between 4 and 8 degrees Celsius for up to one week, ensuring proper moisture retention.
      • Regarding the fluorescence capabilities of the microscope, the light emitted by the mercury lamp of the microscope is used in conjunction with filters that have average wavelengths of 366, 477, 546, and 579 nm. These specific wavelengths can be employed for excitation and to facilitate the visualization of desired fluorochromes. The microscope's lenses offer magnifications of ×4, ×10, ×20, ×40, and ×100.
2. The Olympus CKX41 inverted microscope, equipped with a highly sensitive DP71 camera, allows for the observation and photography of cell samples within cell culture plates or flasks using both the optical and fluorescence sections. The microscope lenses can be utilized at three magnifications of ×4, ×10, and ×40. Additionally, this microscope is equipped with two filters with average wavelengths of 477 nm and 546 nm for the excitation of desired fluorochromes. This laboratory has a long and successful history in photographing animal and plant cell samples, as well as transparent synthetic samples, with a maximum resolution of 500 nm.
