Summary Introduction
Introduction:
For staining a specimen, a smear or a thin film of the specimen is made on a slide. This slide is then heat fixed for adhesion of the specimen with the slide. Basic dyes or acidic dyes are used for staining different parts of the specimen to enhance visualization of the specimen.
