scFv Single Chain Antibody Variable Fragment as Inverse Agonist of the β2-Adrenergic Receptor

Fragment (scFv) Specific for Intercellular Lactobacilli-Expressed Single-Chain Variable

Generation of a Single Chain Antibody Variable Fragment (scFv) to Sense Selectively RhoB Activation

Determining the cellular level of activated form of RhoGTPases is of key importance to understand their regulatory functions in cell physiopathology. We previously reported scFvC1, that selectively bind to the GTP-bound form of RhoA, RhoB and RhoC. In this present study we generate, by molecular evolution, a new phage library to isolate scFvs displaying high affinity and selectivity to RhoA and...

Production of human single-chain variable fragment (scFv) antibody specific for digoxin by ribosome display.

Ribosome display was applied in vitro to select single-chain variable fragment (scFv) antibody specific for digoxin from a human non-immune naive scFv library. A cell-free system was used to produce stable antibody-ribosome-mRNA (ARM) complexes to provide the linkage of genotype and phenotype, allowing simultaneous selection of a desired antibody together with its encoding mRNA. The mRNA was th...

RECOMBINANT SINGLE CHAIN VARIABLE FRAGMENT ANTIBODIES (scFv) AGAINST Pro144-Leu155 FRAGMENT OF HUMAN PROTEIN C.

The aim of this work was to obtain the recombinant single chain variable fragments of antibodies (scFv) against human protein C, the key component of blood anticoagulation system. For this purpose a peptide that mimics a Pro144-Leu155 sequence of protein C was synthesized and the murine immune scFv library against this peptide was constructed. The protein C specific scFv 9E were selected from t...

Design and Construction of a Novel Humanized Single-Chain Variable-Fragment Antibody against the Tumor Necrosis Factor alpha

The pro-inflammatory cytokine, TNF-α, which plays a major role in the development and persistence of inflammatory diseases, is the basis for the use of anti-TNF-α therapies. The neutralization of TNF-α or blockage of its binding to the corresponding receptor has mainly served as a therapeutic strategy against some diseases. This study aimed to investigate the production of a humanized single ch...
