title: In situ monitoring of peptide-bound dsDNA selection on a GCN4-bZIP-immobilized quartz-crystal microbalance.
abstract: A highly sensitive 27 MHz quartz-crystal microbalance (QCM) was applied as a device of dsDNA in vitro selection. When GCN4-bZIP peptides were immobilized on the small Au electrode of the QCM, dsDNAs having TGACTCA sequences could be mainly selected from DNA library having a 15-bp random region, which was consistent with the sequence observed by X-ray crystallography.
