Summary Introduction
Introduction:
Staining is a coloring procedure in which a dye is used to color the specimen in order to highlight the specific structures of the specimens. Based on the requirements of the specimen study, different types of staining procedures were followed. Negative staining is a procedure followed to obtain the accurate morphology of a cell, as it stains only the background and not the specimens.
