Nuclear Staining by Giemsa stain – Procedure, Principle, Result
3 min read 
Bacterial cells contain nuclear material, made of single-stranded circular DNA, in contrast to eukaryotes. This genetic material is present within the membrane-bounded structure known as the nucleus. In case of prokaryotes the nuclear material is present within the nucleoid which lacks the nuclear membrane and does not follow the mitosis or miosis cell division. Some … Read more
Cell Membrane Staining Procedure, Principle, Result
3 min read 
The cell membrane is a biological membrane which also termed a plasma membrane (PM) or cytoplasmic membrane. It divides the interior of the cell from the outside environment, thus protects the cell from environmental stress. The cell membrane is a lipid bilayer, contains cholesterols between phospholipids which maintain their fluidity at various temperatures. The membrane … Read more
