Isotope-Labeled Nucleic Acids

Nucleic acids, comprising of nucleobases, nucleosides, and nucleotides, are biopolymers, macromolecules, essential to all known forms of life. The two main classes of nucleic acids are deoxyribonucleic acid ( DNA ) and ribonucleic acid ( RNA ), both of which serve as the genetic information-carrying molecules. MedChemExpress ( MCE ) offers various Stable Isotope-Labeled nucleic acids and derivatives to assist protein structural analysis and DNA/RNA related researches.
