Postponement of G-Chron 2020
Due to delays in the preparation of the materials for Round 2 of the G-Chron programme, we will not be able to start this round in 2020. Currently our best estimate for sample dispatch is around the middle of 2021. We sincerely regret the delays that we are experiencing due to the current global health crisis.
