A Bifunctional Protein G-Streptavidin Fusion Protein for Antibody Detection and Circulating Tumor Cell Enrichment.
Circulating tumor cells (CTCs) are important biomarkers of cancer metastasis; however, their extremely low abundance in the bloodstream poses significant challenges for sensitive and specific detection. Bifunctional fusion proteins that combine an IgG-binding domain with a signal-amplifying module offer a promising str...
