Dynamic changes in DNA populations revealed by split-combine selection.
Ontology highlight
ABSTRACT: Clickmers are chemically modified aptamers representing an innovative reagent class for developing binders for biomolecules with great impact on therapeutic and diagnostic applications. To establish a novel layer for screening various chemical entities, we developed a split-combine selection strategy simultaneously enriching for clickmers having different modifications. Due to the inherent design of this strategy, dynamic changes of DNA populations are traceable at an individual sequence level. Besides off-rate guided enrichment, the process makes the survival of the sequences most adapted to the applied selection condition observable. The underlying strategy provides unprecedented molecular insight into the selection process, based on which more sophisticated procedures will become pliable in the future.
