Aminoallyl-dUTP is used for indirect stable labeling of DNA/cDNA by polymerase chain reaction (PCR) with Taq polymerase, Nick Translation with DNAse I/ DNA Polymerase I, Primer Extension with Klenow exo-, 3'-End Labeling with Terminal deoxynucleotidyl Transferase (TdT) and Reverse Transcription with MMLV Reverse Transcriptase. It is enzymatically incorporated into DNA/cDNA as substitute for its natural counterpart dTTP. The resulting Amine-functionalized DNA/cDNA can subsequently be labeled via the classic Amine/NHS Ester reaction that introduces a Biotin group (via NHS Ester of Biotin) for subsequent purification tasks or introduces fluorescent group (via NHS Ester of fluorescent dyes) for subsequent microscopic imaging and dot blots (cDNA probes) [1][2].

Aminoallyl-dUTP can also be introduced to probe by PCR and functions as a reactive site for subsequent labeling of the probe. The fluorescent labeling probe is used for in situ hybridization [2].
