How are cells stained and samples prepared?

Cell staining techniques and preparation depend on the type of staining agent and analysis method. One or more of the following procedures may be necessary to prepare a sample:
• Permeabilization - treatment of cells, usually with a mild surfactant that dissolves cell membranes to allow larger dye molecules to enter the cell

• Fixation - serves to "fix" or maintain cell or tissue morphology through the perparation process. This process can include several steps, but most fixation procedures involve adding a chemical fixative that creates chemical bonds between proteins to increase their strength. Common fixatives include formaldehyde, ethanol, methanol, and/or picric acid

• Mounting - involves attaching samples to a slide for observation and analysis. Cells can be grown directly on the slide or single cells can be applied to a slide using sterile techniques. Thin sections (slices) of material - such as tissue - can also be placed on a microscope slide for observation

• Staining - the application of staining agent to cells, tissues, components, or metabolic processes of cells to color. This method may include immersing the sample (before or after fixing or mounting) in a dye solution and then rinsing and observing the sample under a microscope. Some dyes require the use of an etchant, which chemically reacts with the colorant to produce an insoluble colored result. The etched dye will remain on/in the sample when the excess dye solution is rinsed away
