Oral administration of Lactobacillus reuteri expressing a 3D8 single-chain variable fragment (scFv) enhances chicken growth and conserves immune homeostasis

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

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...

Isolation of single chain variable fragment (scFv) specific for Cry1C toxin from human single fold scFv libraries.

As bioinsecticides Bacillus thuringiensis Cry1C δ-endotoxins also have been used in genetically modified crops worldwide since last century. In this study, single chain variable fragments (scFvs), which could specifically recognize and detect Cry1C in food samples, were isolated from naive phage displayed human antibody libraries (Tomlinson I + J) by iterative affinity selection procedure inste...

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...

Generation and immune-characterization of single chain fragment variable (scFv) antibody recognize breast cancer cells line (MCF-7)

Phage display technologies were used to produce singlechain antibodies (scFv) against breast cancer cell line (MCF-7). The mouse B cell hybridoma line C3A8 was the starting material, which generates a monoclonal antibody against breast cancer cells (MCF-7). The best candidate scFv sequences, based on (ELISA) screening data were sub-cloned into HB2151 host strain. The scFv gene was expressed in ...
