Selection, alkaline phosphatase fusion, and application of single-chain variable fragment (scFv) specific to NT-proBNP as electrochemical immunosensor for heart failure

open access: yesHeliyon, 2023
Heart failure has a high global prevalence, with symptoms such as breathlessness, fatigue, and swelling. Early detection is crucial, as the condition worsens over time and can be fatal. This study identified the single-chain variable fragment (scFv) that

Combinations of Single Chain Variable Fragments From HIV Broadly Neutralizing Antibodies Demonstrate High Potency and Breadth

open access: yesFrontiers in Immunology, 2021
Broadly neutralizing antibodies (bNAbs) are currently being assessed in clinical trials for their ability to prevent HIV infection. Single chain variable fragments (scFv) of bNAbs have advantages over full antibodies as their smaller size permits ...

A Cassette Vector System for the Rapid Cloning and Production of Bispecific Tetravalent Antibodies

open access: yesAntibodies, 2012
Bivalent single chain (sc)Fv-Fc antibodies have been used for years as recombinant alternatives of natural immunoglobulins. We have extended this approach to the scFv-Fc-scFv antibody format to obtain tetravalent antigen binding and the possibility to ...

Fusion Expression and Affinity Identification of Two scFvs Against CEA or CA19-9 in HEK293 Cells

open access: yesZhongliu Fangzhi Yanjiu, 2019
Objective To express two scFv-Fc fusion proteins of anti-CEA scFv-Fc and anti-CA19-9 scFv-Fc in HEK293 cells efficiently, and to determinate the affinity of two single chain antibodies. Methods Two scFv gene sequences obtained from GenBank were optimized

Complementarity determining regions and frameworks contribute to the disulfide bond independent folding of intrinsically stable scFv. [PDF]

open access: yesPLoS ONE, 2017
CyDisCo is a system facilitating disulfide bond formation in recombinant proteins in the cytoplasm of Escherichia coli. Previously we screened for soluble expression of single chain antibody fragments (scFv) in the cytoplasm of E.

Use of Single-Chain Antibody Derivatives for Targeted Drug Delivery

open access: yesMolecular Medicine, 2016
Single-chain antibodies (scFvs), which contain only the variable domains of full-length antibodies, are relatively small molecules that can be used for selective drug delivery.
