Fig. 4From: Assembly and use of high-density recombinant peptide chips for large-scale ligand screening is a practical alternative to synthetic peptide librariesUncovery of novel Streptavidin binders by recombinant peptide chips. a Excerpt of a random peptide chip (5 technical replicates each), resulting in the discovery of F14.5. Positive controls were included for simultaneous semi-quantitative evaluation of binding strengths. An in parallel performed GST-blot reveals relatively homogenous peptide expression levels. b Dimerisation of B5 and F14.5, analyzed by recombinant peptide chipBack to article page
