Q-banding: The Q-banding name is given by the use of quinacrine fluorescent dye in the banding technique. The present method is similar to the G-banding, however, here the fluorescent dye is utilized instead of a normal dye. ... It is specific for the phosphate groups of DNA and attaches itself to regions of DNA where there are high amounts of adenine-thymine bonding. Giemsa stain is used in Giemsa banding, commonly called G-banding, to stain chromosomes and often used to create a karyogram (chromosome map). It can identify chromosomal aberrations such as translocations and rearrangements.
WebIn case of vital staining, water soluble non-toxic dyes (methylene blue) are applied to the living tissue so that the latter can be studied without being killed. In non-vital staining, the colouration of the chromosomes and other cell constituents in the killed tissue is caused by certain chemicals which are insoluble in chromosome substance ... WebFluorescence SpectraViewer DAPI (4′,6-diamidino-2-phenylindole) is a blue-fluorescent DNA stain that exhibits ~20-fold enhancement of fluorescence upon binding to AT regions of dsDNA. It is excited by the violet (405 nm) laser line and is commonly used as a nuclear counterstain in fluorescence microscopy, flow cytometry, and chromosome staining.
