Applications:


HPLC Separation of Nucleic Bases at pH 4 and 5 on Obelisc N

Nucleic bases are biological compounds found in genetic molecules (DNA, RNA). They can be separated on an Obelisc N column, which offers very polar characteristics and can be used with positively or negatively charged groups. Closely-eluted adenosine and uridine can be further separated by simply adjusting the pH of the mobile phase. Mobile phase is water and acetonitrile (MeCN, ACN) with Ammonium Acetate as buffer. UV detection at 250nm. 

Application Analytes:

Adenosine
Cytidine
Cytosine
Guanosine
Uracil
Uridine

HPLC Separation of Thymidine, Uridine, Adenosine, Guanosine, and Cytidine Using the Hydrogen Bonding Method

 

Application Notes: Nucleosides are glycosylamines consisting of nucleobase linked to ribose or deoxyribose sugar and are building blocks for DNA and RNA. These compounds are very polar and contain groups available for hydrogen bonding interaction. Thymidine, uridine, adenosine, guanosine and cytidine were separated using a hydrogen-bonding method. There is a strong correlation between the retention time and mobile phase composition. The strength of hydrogen-bonding interaction increases as the number of hydroxyls in the analytes increase. Additionally the rder of elution for compounds depends on the ratio of the mobile phases: acetonitrile and methanol. Our method is compatible with LC/MS and preparative chromatography.
