CAR (Chimeric Antigen receptor)-T cell therapy is a novel type of therapy that uses engineered T cells with an antibody single-chain variable fragment (ScFv) extracellular domain that binds tumor-associated antigens[...].

By constructing Fv and single-chain Fv (scFv) fragments of antibodies, the variable domains are taken out of their natural context in the Fab fragment, where they are associated with the constant domains of the light (CL) and heavy chain (CH1). As a consequence, all residues of the former variable/constant domain interface become solvent exposed. In an analysis of 30 non-redundant Fab structure...

A recombinant single-chain molecule, scFv-K12G0, containing the variable domains of the monoclonal antibody MA-15C5, specific for fragment D-dimer of human cross-linked fibrin, was constructed and expressed in Spodoptera frugiperda, Sf9, insect cells. The Arg108 carboxyl-terminal amino acid of the variable domain of the light-chain of the antibody was connected through a synthetic Ala-Gly-Gln-G...

Recent advances in the use of gold nanoparticles (Au NPs)/antibody conjugations nanomedicine have increased need to optimize synthesis conditions and surface functionalization Au NPs. In this study, a home-made Neisseria meningitidis recombinant antibody (scFv-Fc) was developed by connecting fragment crystallizable (Fc) region human with mouse (single-chain variable (scFv)) characterized using ...

background:epidermal growth factor receptor (egfr) overexpression is a characteristic of several malignancies and could be considered as an excellent target for designing specific inhibitors such as anti-egfr monoclonal antibodies for cancer therapy. drawbacks exerted by large sizes of full-length antibodies have lead to the development of single chain antibodies, which benefit from having smal...

To determine malachite green (MG) and its major metabolite, leucomalachite (LMG) residual levels in tilapia fish, chemiluminescent enzyme immunoassay (CLEIA) was developed based on a single-chain variable fragment (scFv)-alkaline phosphatase (AP) fusion protein. At first, VH VL gene sequences were cloned from hybridoma cell lines secreting monoclonal antibody against LMG, then thoroughly by dat...

Phage-displayed single chain variable fragment (scFv) libraries have been powerful tools in antibody engineering. But the scFv structures are frequently unstable due to the dissociation of the dimeric interface between the two variable domains. One solution is the sc-dsFv construct, where the single chain variable domain fragment is stabilized with an additional interface disulfide bond, leadin...
