Selection of single-chain variable fragments specific for Mycobacterium tuberculosis ESAT-6 antigen using ribosome display
Objective(s): Tuberculosis (TB) is still one of the problematic infectious diseases in developing countries, especially in Iran. In the present study, we applied ribosome display technique to select single chain variable fragments (scFvs) specific for the 6-kDa early secretory antigenic target (ESAT-6) antigen of Mycobacterium tuberculosis from a mouse scFv library. Materials and Methods: The g...
متن کاملRibosome display: a perspective.
Ribosome display is an in vitro evolution technology for proteins. It is based on in vitro translation, but prevents the newly synthesized protein and the mRNA encoding it from leaving the ribosome. It thereby couples phenotype and genotype. Since no cells need to be transformed, very large libraries can be used directly in selections, and the in vitro amplification provides a very convenient i...
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 کاملSelection of Diethylstilbestrol-Specific Single-Chain Antibodies from a Non-Immunized Mouse Ribosome Display Library
Single chain variable fragments (scFvs) against diethylstilbestrol (DES) were selected from the splenocytes of non-immunized mice by ribosome display technology. A naive library was constructed and engineered to allow in vitro transcription and translation using an E. coli lysate system. Alternating selection in solution and immobilization in microtiter wells was used to pan mRNA-ribosome-antib...
