Self-quenching dye

WebNov 15, 2024 · When the concentration of a fluorescent substance is too large, a self-quenching phenomenon will occur. The fluorescence quenching phenomenon needs to be considered in the fluorescent dye labeling experiments of macromolecules. When labeling, the ratio of macromolecule/dye needs to be controlled. Do not over-label. WebOct 30, 2000 · self-quenching between dye molecules, instead of change in fluorescence properties of the dye under different solution conditions. Because of the compactness of the three-dimensional structure of native titin, the dye molecules are in close proximity with each other and their fluorescence is severely quenched. After unfolding, the protein ...
