چکیده

Inexpensive, simple and quick detection of pathogen antigens in human samples is a key global health objective. Limiting factors include the cost and complexity of diagnostic tests that utilize antibody probes. Herein, we present a method for label-free electrochemical detection of a protein from the enteric pathogen Entamoeba histolytica using cell-free yeast-embedded antibody-like fragments (yeast-scFv) as novel affinity reagents.

Toward Low-Cost Affinity Reagents: Lyophilized Yeast-scFv Probes Specific for Pathogen Antigens

The generation of affinity reagents, usually monoclonal antibodies, remains a critical bottleneck in biomedical research and diagnostic test development. Recombinant antibody-like proteins such as scFv have yet to replace traditional monoclonal antibodies in antigen detection applications, in large part because of poor performance of scFv in solution. To address this limitation, we have develop...

Designing a Label Free Aptasensor for Detection of Methamphetamine

A label-free electrochemical nucleic acid aptasensor for the detection of methamphetamine (MA) by the immobilization of thiolated self-assembled DNA sequences on a gold nanoparticles-chitosan modified electrode is constructed. When MA was complexed specifically to the aptamer, the configuration of the nucleic acid aptamer switched to a locked structure and the interface of the biosensor changed...
