About the meeting

Following one year gap enforced by COVID pandemics, the G4 community is trying to restore the International Meeting on Quadruplex Nucleic Acids tradition. The meeting has been the major conference series in guanosine self-assembly, G-quadruplexes, and other unusual nucleic acid motifs since 2007.

We are happy to inform you of the "8th International Meeting on Quadruplex Nucleic Acids" in Marienbad (Czech Republic) from June 27th to July 1st, 2022. Please save the date in the calendar!!!

Our mission is to organize a fully live event. A specific focus of the 2022 meeting will be on G-quadruplex biology.


Looking forward to meeting you in Marienbad!
