FISH (fluorescence in-situ hybridisation) is a molecular cytogenetic technique that enables the detection and localisation of specific DNA sequences in cells or tissues. It is often used in clinical applications such as cancer diagnosis and prognosis.

The copper(I)-catalysed azide-alkyne cycloaddition (CuAAC) is the most prominent example of a group of reactions named click reactions. According to Sharpless’ definition, these reactions are characterised by high yields, mild reaction conditions, and by their tolerance of a broad range of functional groups.[1-3] Typically, the reactions require simple or no workup or purification of the product. The most important characteristic of the CuAAC reaction is its unique bioorthogonality as neither azide nor terminal alkyne functional groups are generally present in natural systems.
