Cross-Neutralization Activity of Single-Chain Variable Fragment (scFv) Derived from Anti-V3 Monoclonal Antibodies Mediated by Post-Attachment Binding

Molecular immunolabeling with recombinant single-chain variable fragment (scFv) antibodies designed with metal-binding domains.

To study the molecular structure and function of gene products in situ, we developed a molecular immunolabeling technology. Starting with cDNA from hybridomas producing monoclonal antibodies against biotin, catalase, and superoxide dismutase, we bioengineered recombinant single-chain variable fragment antibodies (scFv) and their derivatives containing metal-binding domains (scFv:MBD). As tested...

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) antibodies against synthetic peptide fragments of human cathepsin S.

This transaction reports on the on-going attempt to isolate anti-peptide scFv antibodies from an scFv phage-display library capable of detecting the native protein from which the peptide sequence was derived. The display of antibody fragments on the surface of filamentous bacteriophage by fusion to the minor coat protein (plll) and selection of phage with antigen, has provided a powerful method...

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

Phage-display derived single-chain fragment variable (scFv) antibodies recognizing conformational epitopes of Escherichia coli heat-labile enterotoxin B-subunit.

Previously we have described studies on in vitro pentamer assembly of Escherichia coli (E. coli) derived heat-labile enterotoxin B subunit (EtxB) using conventional monoclonal antibodies (Amin et al., JBC 1995: 270, 20143-50 and Chung et al., JBC 2006: 281, 39465-70). To extend these studies further we have used phage-display to select single-chain Fragment variable (scFv) antibodies against di...
