Most species of bacteria can be broadly divided into two groups, known as gram-positive and gram-negative. These categories ...

Negative staining is a powerful preparative method for studying particulate specimens. In principle, the specimen is surrounded by heavy metal atoms that act as an electron barrier. Because the ...

NEGATIVE staining has become widely accepted as a means of visualizing macromolecular structures under the electron microscope1,2. Its advantages lie in its simplicity and the high contrast which ...

Gram staining is a type of differential staining used to distinguish between Gram positive and Gram negative bacterial groups, based on inherent differences in their cell wall constituents. Stains ...
