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.

Application
Aminoallyl-dUTP-XX-AF488 is a modified thymidine analog designed for fluorescent nucleic acid labeling workflows, combining an aminoallyl functional handle with an Alexa Fluor 488 (AF488) fluorophore. This reagent supports post-incorporation fluorescent tagging of DNA using aminoallyl chemistry, enabling researchers to generate labeled probes for fluorescence microscopy, hybridization-based assays, and nucleic acid tracing with green excitation/emission. The AF488 dye provides a widely used fluorescence channel for imaging and readout in standard fluorescence instrumentation.
1. Fluorescent DNA Labeling
Aminoallyl-dUTP-XX-AF488 is used by molecular biology and genomics labs to introduce an AF488 fluorophore into DNA during probe preparation, supporting fluorescently labeled DNA targets for downstream hybridization and imaging experiments. Researchers commonly incorporate the dUTP analog into DNA templates or generate labeled amplicons for visualization of nucleic acid localization in fixed samples or for tracking DNA in assay workflows. The aminoallyl functionality is particularly valued in labeling strategies where a fluorophore-conjugated nucleic acid is required while maintaining compatibility with established nucleic acid handling and hybridization protocols.
2. Fluorescence In Situ Hybridization
Aminoallyl-dUTP-XX-AF488 is applied in fluorescence in situ hybridization (FISH) workflows to produce AF488-labeled DNA probes for microscopy-based detection of nucleic acid sequences in cells or tissue sections. Laboratories use the green channel provided by AF488 to localize specific genomic regions or transcripts in a spatially resolved manner, often in multiplex experiments where AF488 is paired with spectrally distinct fluorophores. This reagent is therefore a practical choice for researchers developing hybridization probes that require robust fluorescence readout under standard fluorescence microscopy conditions.
3. qPCR and Amplification Tracing
Aminoallyl-dUTP-XX-AF488 supports fluorescence-based nucleic acid amplification and tracing applications where AF488-labeled DNA products are used as a measurable fluorescence output. Researchers in molecular diagnostics R&D and assay development teams use AF488-labeled nucleic acids to monitor amplification products, validate probe performance, and support fluorescence readouts in nucleic-acid workflows that rely on green-channel detection. The reagent's nucleic acid-compatible design helps streamline the preparation of fluorescent DNA materials for assay optimization and method development.
4. Flow Cytometry DNA Analysis
Aminoallyl-dUTP-XX-AF488 is used in flow cytometry-oriented nucleic acid analysis workflows that require fluorescently labeled DNA for population-level readout. In research settings, AF488-labeled nucleic acids can be used to quantify or compare nucleic acid-associated signals across cell populations, including assay development experiments where fluorescent labeling chemistry must integrate with sample processing and instrument detection. This application is particularly relevant for teams optimizing fluorescence labeling conditions for nucleic acid measurements using standard blue/green excitation and AF488-compatible emission detection.
