Cresyl violet stained partial brain section of a Macaque. It is used in biology and medicine as a histological stain. Cresyl violet is an effective and reliable stain used for light microscopy sections. Initially, tissue sections are "defatted" by passing through graded dilutions of ethanol. Then, rehydrated by passing back through decreasing ...
Crystal violet stains both Gram positive and Gram negative organisms. Treatment with alcohol removes the crystal violet colour from gram negative organisms only. Safranin as counterstain is used to colour the gram negative organisms that got decolorised by alcohol. While ex vivo, many cells continue to live and metabolize until they are "fixed".
Gram-positive cells have a thick layer of peptidoglycan in the cell wall that retains the primary stain, crystal violet. Gram-negative cells have a thinner peptidoglycan layer that allows the crystal violet to wash out on addition of ethanol. They are stained pink or red by the counterstain, [3] commonly safranin or fuchsine.
Crystal violet or gentian violet, also known as methyl violet 10B or hexamethyl pararosaniline chloride, is a triarylmethane dye used as a histological stain and in Gram's method of classifying bacteria.

You could save this video to show to anyone who uses that phrase, and you'll catch them off guard for sure. Sadly, viewers won't see Petunia the pink piglet fly for very long.
Thus, when heat shock is applied, the negatively charged DNA backbone and LPS combine, allowing plasmid DNA to enter the bacterial cell. [13] The process is summarized in the following steps according to The Undergraduate Journal of Experimental Microbiology and Immunology (UJEMI) protocol: Prepare a bacterial culture in LB broth
