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. WebDNA sequence (satellite DNA) is used to stain by C-binding technique. After staining, banding is viewed by bright-field microscope. 4. R-banding: R-banding is called Reverse chromosome banding.
