Nucleic Acid Analyzer

Nucleic acids are the building blocks of life in all living things, from plants and animal to bacteria and viruses.  In research, it’s important to ascertain the purity of DNA and RNA samples prior to downstream processes.  Proteins and other contaminants like phenol and salts may interfere with the sample and produce a lower absorbance ratio.  This informs users that contaminants are present in the sample and allows a change to be made before contaminated sample ends up in downstream processes.  Fortunately, CST’s Nucleic Acid Analyzer is designed for continuous, real-time monitoring of nucleic acid purity.
