It has a few side effects. Basic stains with a positively charge chromogen are preferred because bacterial nucleic acid and certain cell wall components carry a negative charge that strongly attract and binds to the cationic chromogen. Therefore, counting errors (~10%) could be occurred. The advantages of the negative stain include the use of only one stain and the absence of heat fixation of the sample. Mucin stains By using a variety of different stains, you can selectively stain different areas such as a cell wall, nucleus, or the entire cell. Differential staining allows one to differentiate G+ from G- cells, whereas simple staining only shows cell size and morphology. Testing showed that the harsh constituents of the iron stain working solution reduced the staining intensity of the IHC chromogens when used subsequently.
