Guanosine monophosphate

Separation of Nine Nucleotides with Core-Shell Mixed-Mode Column
Application description

Core-shell columns are able to handle higher flow-rates, while maintaining high efficiency and low back-pressure. Coresep SB was used to achieve separation of nine nucleotides. The strong embedded basic ion-pairing groups make it possible to separate compounds that don’t retain on reverse-phase columns.
