Aminoallyl-dUTP-XX-AF488

Product Introduction

Aminoallyl-dUTP-XX-AF488 is recommended for direct enzymatic labeling of DNA/cDNA e.g. by PCR and Nick Translation. It is incorporated as substitute for its natural counterpart dTTP. The resulting Dye-labeled DNA/cDNA probes are ideally suited for fluorescence hybridization applications such as FISH or microarray-based gene expression profiling.Optimal substrate properties and thus labeling efficiency is ensured by an optimized linker attached to the C5 position of uridine. AF488 (also known as Alexa Fluor 488®) is a hydrophilic dye with excellent photostability compared to fluorescein.
