Molecular engineering of biotin-glutamic acid decarboxylase 65 fusion protein (Biotin-GAD65) for non-radioactive GAD65 antibody assay

Research output: Contribution to journalArticle

Abstract

We constructed biotinylated fusion proteins that linked to three detection tags to GAD65 at the N-terminus, and expressed them in an E. coli expression system. The Biotin14-GAD65 protein exhibited the strongest binding to both the GAD65 antibody and the streptavidin among the three constructs. We describe the optimal conditions using a Biotin14-GAD65-based immunoassay for the detection of GAD65 antibody.
