Ribosome display efficiently selects and evolves high-affinity antibodies in vitro from immune libraries.
Ribosome display was applied for affinity selection of antibody single-chain fragments (scFv) from a diverse library generated from mice immunized with a variant peptide of the transcription factor GCN4 dimerization domain. After three rounds of ribosome display, positive scFvs were isolated and characterized. Several different scFvs were selected, but those in the largest group were closely re...
متن کاملRibosome display: an in vitro method for selection and evolution of antibodies from libraries.
Combinatorial approaches in biology require appropriate screening methods for very large libraries. The library size, however, is almost always limited by the initial transformation steps following its assembly and ligation, as other all screening methods use cells or phages and viruses derived from them. Ribosome display is the first method for screening and selection of functional proteins pe...
متن کاملRapid selection of high-affinity binders using ribosome display.
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...
متن کاملIn-vitro protein evolution by ribosome display and mRNA display.
In-vitro display technologies combine two important advantages for identifying and optimizing ligands by evolutionary strategies. First, by obviating the need to transform cells in order to generate and select libraries, they allow a much higher library diversity. Second, by including PCR as an integral step in the procedure, they make PCR-based mutagenesis strategies convenient. The resulting ...
متن کاملHigh-throughput method for ranking the affinity of peptide ligands selected from phage display libraries.
The use of phage display peptide libraries allows rapid isolation of peptide ligands for any target selector molecule. However, due to differences in peptide expression and the heterogeneity of the phage preparations, there is no easy way to compare the binding properties of the selected clones, which operates as a major "bottleneck" of the technology. Here, we present the development of a new ...
