Bacterial smears that are undergoing some type of differential staining method are stained with a primary dye. Primary dye typically refers to a Crystal-voilet stain that is used in the gram staining procedure to color all cells purple. After a mordant (iodine-makes the dye complex less soluble), decolorizer, and a counterstain are added to the primary dye, a person can view the slide under a microscope in order to distinguish gram-positive bacteria from gram-negative bacteria. The cell wall of gram-negative bacteria will not retain the primary dye and be washed away with the decolorizer. Gram-neg. bacteria will then take on the counterstain providing contrast between the two types of bacteria when viewed under a microscope.

How does nigrosin stain work?
Nigrosin stain is an acidic, anionic dye that works by staining the background of a sample, allowing for better contrast with the stained structures. It is commonly used in microbiology for negative staining techniques to highlight the morphology and arrangement of bacterial cells. The dye is repelled by the negatively charged bacterial cell walls, resulting in a clear outline of the cells against the stained background.
How many genes might a band stained with giemsa dye on a chromosome contain?
A band stained with Giemsa dye on a chromosome typically represents a region that can contain hundreds to thousands of genes, depending on the size of the band and the specific chromosome. Generally, larger bands may encompass more genes, while smaller bands may contain fewer. On average, a single Giemsa-stained band might house anywhere from a few to several dozen genes. The exact number can vary significantly among different chromosomes and organisms.
What are pre-stained proteins?
Prestained proteins are proteins that are already stained permanently so they are visible while running the gel.
