Zusammenfassung:A marker for marking a predetermined structure within a biological sample includes an affinity reagent configured to attach to the predetermined structure, a linker structure attached to the affinity reagent and extending from the affinity reagent, and at least two different fluorescent dyes arranged at the linker structure. The linker structure includes at least one cleavage site arranged between the two fluorescent dyes or between one of the fluorescent dyes and the linker structure. The linker structure is capable of being cut at the cleavage site by a cleaving agent in order to remove at least one of the fluorescent dyes from the marker.
