New Serology Assay Accelerates COVID-19 Research through Rapid Characterization of Immune Response to SARS-CoV-2 Antigens

Bio-Techne Corporation (Minneapolis, Minn., USA) has launched its SARS-CoV-2 Multi-Antigen Serology Module for Jess and Wes Simple Western automated western blotting systems. ProteinSimple's Simple Western systems are automated, hands-free western blotting platforms that can be used for antigen-down serology assays for SARS-CoV-2. The Simple Western serology assay moves beyond 1- or 2-antigen serology assays to measure serum or plasma antibodies reactive against five SARS-CoV-2 antigens simultaneously, providing information-rich views into antibody binding profiles across patients and over the time course of the infection. The SARS-CoV-2 multi-antigen serology assay runs on Jess and Wes systems, enabling the processing of 23 patient samples in three hours. This approach has promise as a tool to rapidly characterize patient immune response and as an orthogonal confirmatory test to validate results derived from lateral flow, ELISA (enzyme-linked immunosorbent assay) or other immunoassay serology techniques.

"We are excited about the multi-antigen views this serology assay provides COVID-19 researchers and vaccine developers, while promising to speed up time to data," said Bob Gavin, Sr. Vice President of Bio-Techne's, Analytical Solutions Division. "It leverages Simple Western strengths of minimal set-up time, hands-free operation, and fully analyzed results in three hours."

"The new SARS-CoV-2 Multi-Antigen Serology Module is a powerful advancement in the fight against COVID-19," said Dave Eansor, President of Bio-Techne's Protein Sciences Segment. "At Bio-Techne, we are committed to arming COVID-19 vaccine developers and scientists researching the SARS-CoV-2 immune response with cutting edge technology including the new Simple Western serology assay and Kantaro SeroIndex RUO ELISA kit."
