Aminoallyl-dUTP sodium salt has been used:to add to the deoxynucleoside triphosphate mix for complementary DNA (cDNA) synthesisfor the generation of chromatin immunoprecipitation (ChIP) probesin the reverse transcription of RNA for the synthesis of fluorescent labelled probesAminoallyl-dUTP may be used for indirect stable labeling of first-strand cDNA synthesis via polymerase chain reaction (PCR). Aminoallyl-dUTP functions as a reactive site for subsequent labeling by reactive fluorescent probes. Aminoallyl-dUTP may also be useful in the construction of reactive DNA scaffolds.
