HPLC Application for Separation of Nucleotide Bases
Nucleotide bases are parts of DNA and RNA. Adenine and guanine are purine-bases; uracil, thymine and cytosine are pyrimidine-bases. In the view of chromatography these compounds are very polar and similar in properties. It is hard to obtain base line separation on traditional C18 as peaks of nucleotide bases co-elute even at low organic concentration. In this application nucleobases are well retained and separated on Primesep 200 mixed-mode column. Compounds are retained by weak reverse phase and weak ion-exchange mechanisms. Method can utilize UV, ELSD, and LC/MS detection.

HPLC Separation of Adenosine and Adenine Using the Hydrogen Bonding Method



Application Notes: Nucleosides are glycosylamines consisting of a nucleobase linked to a ribose or a deoxyribose sugar. Nucleoside are building blocks for DNA and RNA. These compounds are very polar in nature and contain groups available for hydrogen bonding interactions. Method for separation of adenine and adenosine were developed using a hydrogen-bonding method. There is a strong correlation between retention time for adenine/adenosine and the mobile phase composition, which consists of acetonitrile and methanol. Order of elution for compounds depends on the amount of acetonitrile and methanol.  Furthermore, ellution of adenine and adenosine can be reversed based on the composition of the mobile phase. Our method is compatible with LC/MS and preparative chromatography.
