Fluorescent Dyes  >  Labeling and Detection of Nucleotides and Nucleic Acids
The detection of nucleic acids is an indispensable step for many life science research tasks, such as sequencing, cDNA synthesis and cloning, RNA transcription and transfection, etc. An inaccurate detection of DNA/RNA may cause these techniques to fail. DNA/RNA concentration is often measured by UV absorbance at 260 nm. This method, however, is not as accurate and sensitive as DNA quantitation by using fluorescent dyes. AnaSpec offers a variety of nucleic acid stains for detecting nucleic acids. These stains can be used for DNA quantitation in solutions or in cells. We also offer reagents for labeling nucleotides and nucleic acids.
