Service description
Negative staining is a simple and rapid method to study the morphology and structure of particulate specimens such as viruses, protein, cell components (e.g., ribosome), cell fragments (e.g., membranes), etc.
The main purpose of negative staining is to surround or embed the biological object in a suitable electron dense material (negative stain) which provides high contrast and good preservation.
The stain (witch is a heavy metal salt) surrounds the specimen and penetrates into open irregularities on the surface of the specimen. The presence of heavy atoms increases electron scattering, thus improving the amplitude contrast.
The specimen and the stain produce different electron scattering, resulting in a light image of the specimen surrounded by a dark background of dried stain.
