Applications of Ion Exchange - Meaning, Method, Uses and FAQs

A crude sample comprising charged molecules makes up the liquid phase. As molecules pass along the chromatographic column, they bond to oppositely charged sites in the stationary phase. To elute the molecules that have been separated based on their charge, a solution of varying ionic strength is utilised.

The formation of the complex stabilises the negatively charged anionic form of the dye, producing the blue colour, even under acid conditions when most of the molecules in solution are in the cationic form. This is the basis of the Bradford assay, which quantifies protein by Coomassie brilliant blue dye binding. The binding of the dye to a ...

Jun 02, 2021 · Acridine orange is a cell-permeable, nucleic acid selective dye that emits green fluorescence when bound to dsDNA (at 520 ) and red fluorescence when bound to ssDNA or RNA (at 650 nm). Since it is a cationic dye, it also enters acidic compartments such as lysosomes which in low pH conditions, will emit orange light.
