Accurate detection and quantification of nucleic acids is fundamental to molecular biology, from basic research to clinical diagnostics. AAT Bioquest provides comprehensive reagents for DNA and RNA analysis, including fluorescent dyes for gel electrophoresis, quantification assays compatible with microplate readers and Qubit™/Cytocite™ instruments, and specialized reagents for PCR applications.
Our Nucleic Acid Detection Technologies
Helixyte™ and Gelite™ proprietary dye families for sensitive nucleic acid detection
Fluorimetric quantification kits optimized for dsDNA, ssDNA, and RNA with picogram-level sensitivity
Safe DNA gel stains as alternatives to ethidium bromide with comparable or superior sensitivity
qPCR calibration solutions and plates for instrument validation across major platforms
Spectral coverage from blue to far-red for flexible multiplexing options
DNA quantification reagents enable precise measurement of double-stranded DNA, single-stranded DNA, and total nucleic acids using fluorescence-based detection. These assays offer superior sensitivity and specificity compared to UV absorbance methods, with detection limits in the picogram range.
