Abstract:
Chemically synthesized peptide arrays on planar cellulosecarriers are proposed as libraries of ligands suitable for the multiplexedsimultaneous capture of peptide-specific acceptor proteins from a largerandomly mutagenized library of acceptor proteins presented onbacteriophage M13 particles. This experimental set-up can be exploited to rapidlyscreen for individual new, distinct binding partners from two complementarylibraries (two-dimensional screening). The technical feasibility of thisempirical protein design approach was demonstrated with calmodulin as anaceptor protein using an array of mastoparan variants for multiplexedphage affinity enrichment.
