Rapid selection of high-affinity binders using ribosome display.


PMID 22094811

Abstract

Ribosome display has proven to be a powerful in vitro selection and evolution method for generating high-affinity binders from libraries of folded proteins. It has been successfully applied to single-chain Fv fragments of antibodies and alternative scaffolds, such as Designed Ankyrin Repeat Proteins (DARPins). High-affinity binders with new target specificity can be obtained from highly diverse DARPin libraries in only a few selection rounds. In this protocol, the selection from the library and the process of affinity maturation and off-rate selection are explained in detail.
