Aminoallyl-dUTP-XX-ATTO-594

Aminoallyl-dUTP-XX-ATTO-594 is an aminoallyl-functionalized thymidine analog bearing an ATTO 594 fluorophore, designed for fluorescent nucleic acid labeling workflows. The aminoallyl handle enables downstream conjugation strategies during oligonucleotide incorporation, supporting fluorescent tracking of DNA/RNA in microscopy and fluorescence-based assays. Its ATTO 594 emission is commonly leveraged for red-channel imaging and fluorescence quantification in molecular biology and chemical biology research.

1. Nucleic Acid Labeling

Aminoallyl-dUTP-XX-ATTO-594 is used by molecular biology teams to incorporate a fluorescent nucleotide analog into DNA during labeling reactions, enabling direct visualization and quantification of nucleic acid samples. Researchers commonly employ this reagent for labeling probes, primers, or experimental DNA constructs where a stable red-emitting dye is advantageous for downstream imaging and readout. The aminoallyl functionality provides a practical route for fluorescence customization and conjugation workflows when building labeled nucleic acid reagents for assays and imaging experiments.

2. Fluorescence Microscopy Probes

Aminoallyl-dUTP-XX-ATTO-594 supports fluorescence microscopy workflows that require nucleic acid-associated signal in the red spectral region. Cell biology and imaging laboratories use ATTO 594-labeled nucleic acid preparations to track hybridization events, visualize labeled DNA/RNA in fixed samples, and generate fluorescent molecular imaging reagents compatible with standard fluorescence microscopes equipped for appropriate excitation/emission channels. This reagent is particularly useful when nucleic acid labeling needs to be integrated into probe generation for spatial studies rather than relying on post-staining dyes.

3. Hybridization and FISH Workflows

Aminoallyl-dUTP-XX-ATTO-594 is frequently incorporated into nucleic acid probes used for hybridization-based detection workflows, including fluorescence in situ hybridization-style applications. Molecular diagnostics research groups and nucleic acid analysis labs use ATTO 594-labeled probe preparations to generate spatially resolved fluorescence signals that report on target nucleic acid presence or localization within prepared samples. The dye's strong performance in red-channel detection helps streamline imaging readouts when multiplexing is planned around spectrally separated fluorophores.

4. Fluorescence-Based Quantification Assays

Aminoallyl-dUTP-XX-ATTO-594 is also applied in fluorescence quantification contexts where labeled nucleic acids serve as reporters for nucleic acid abundance, incorporation efficiency, or hybridization readouts. Biochemistry and chemical biology teams use ATTO 594-labeled nucleic acid reagents in plate-based fluorescence assays and benchtop fluorometry experiments to monitor labeling outcomes and optimize probe conditions. This application is commonly chosen when a robust fluorescent nucleic acid label is needed for consistent signal generation across multiple samples.
