The method of negative staining of uranyl acetate
Fu wants to make clear the shape of micro-matter, and the method of negative staining of uranyl acetate is very good. Prepare the agent of uranyl acetate first, carefully adjust its concentration, and ensure that it is suitable for the object under observation.
Take the sample to be inspected and place it on the glass slide, steady and flat. Slowly drip the uranyl acetate solution on it to cover the sample table. When there are few waiting pieces, let the liquid touch the sample to show its microstructure.
Then, use a filter paper to absorb the liquid, taking care not to damage the sample state. Place the slide under the electron microscope, carefully adjust the parameters, if the focal length and voltage belong, so that the image is clear.
The negative staining of uranyl acetate can also line the contours of microscopic objects, making them clearly recognizable under the mirror. In the study of tiny things, such as viruses and proteins, we rely on this method to understand their mysteries. Helpers explore the secrets of the microscopic and understand the subtle structures of things. In the progress of science, great contributions have been made.
