Developed in 1884 by Danish physician Hans Christian Gram, this method is considered as the most important procedure in microbiology and is still the cornerstone of bacterial identification and the taxonomic division. 5 What are the advantages of using a negative stain? Each stain is useful in its own way for understanding the structure and function of tissues. The main reason you stain a sample before putting it under the microscope is to examine it better, but staining does more than just highlight cell outlines. It aids in the diagnosis of a specific organism and tells the difference between gram negative and gram positive bacteria. By using a variety of different stains, you can selectively stain different areas such as a cell wall, nucleus, or the entire cell. 1. The cell has different parts, and those that can absorb stains or dyes are referred to as chromatic. Haemotoxylin stains certain parts of the cell - like the nucleus - blue; Eosin stains other parts of the cell - such as the cytoplasm - red or pink. These potential IHC development obstacles can take time to overcome, but when the IHC assay is complete, the various chromogens can be visualised simultaneously, using standard light microscopy, and can be viewed repeatedly without altering staining results. You could also do viability stains which is typically an oxymoron because when you stain it, you kill the organism. What are the merits and limitations of simple staining techniques Cons: you have to use a destruction dye to create contrast, you cannot see vital processes (motility) due to the use of a destruction dye.
