WebChromosomes in metaphase can be identified using certain staining techniques, so called banding. Cells are cultured and then stopped in metaphase to maximize the number of suitable cells. They are then spread on a slide, stained with a suitable dye and visualized in the microscope. WebChromosome banding techniques and staining Giemsa has become the most commonly used stain in cytogenetic analysis. Most G-banding techniques require pretreating the chromosomes with a proteolytic enzyme such as trypsin. G-banding preferentially stains the regions of DNA that are rich in adenine and thymine.
