In vitro selection and analysis of RNA aptamer recognize arginine-rich motif (ARM) model peptide on a QCM

Abstract
To study RNA-peptide interactions, we performed an in vitro selection of RNA on a 27 MHz quartz-crystal microbalance (QCM) on which a simple R5 helix peptide was immobilized as a model of N peptide from bacteriophade lambda. The consensus sequences including a GNRA tetraloop were obtained from a random RNA pool after the 7th cycle selection.
