Expanded Collaboration to Improve Syndromic Infectious Disease Testing

MISSISSAUGA, CANADA & IRVINE, CALIFORNIA, December 14, 2023 – Microbix Biosystems Inc. (TSX: MBX, OTCQX: MBXBF, Microbix®), a life sciences innovator, manufacturer, and exporter, announces a collaboration with Seegene USA, Inc. (“Seegene USA”), a leading developer of multiplex molecular assays and automated solutions for U.S. labs. Under the parties’ collaboration, Seegene USA will distribute and recommend Microbix’s Quality Assessment Products (“QAPs™”) to monitor the workflow accuracy of Seegene Novaplex™ and Allplex™ assays in use across the United States.

Microbix QAPs are available to support PCR-based (molecular) assays formatted on Copan® FLOQSwabs® and room-temperature stable, or in liquid vial format that are refrigerator-temperature stable. Microbix PROCEEDx® brand QAPs are Research Use Only “RUO” samples, while its REDx® brand QAPs are In-Vitro Diagnostic “IVD” Controls. Regular use of QAPs helps ensure the accuracy of laboratory-conducted assays.

With this agreement, Seegene USA will begin offering Microbix’s QAPs products, alongside its current portfolio of high multiplex PCR assays that test for infectious disease pathogens under its Allplex™ and Novaplex™ brands. These assays, using Seegene proprietary technology, are unique in their ability to produce high-multiplex results from a single channel in a PCR reaction. In combination, US labs receive an efficient, low-cost approach to achieve high-quality syndromic testing for infectious disease pathogens when compared to currently available options.

Philip Casselli, SVP Business Development, commented, “Our longstanding relationship with Seegene Canada laid a strong foundation for this Microbix – Seegene USA relationship. Our collaboration naturally aligns the two companies to help assure optimal results for laboratories performing high-multiplex PCR testing using Seegene Assays. This week we began our training and comprehensive support of the Seegene USA team.”

“In this partnership, we are again increasing our IVD presence for the U.S. and further supporting our lab customers in their mission to better provide quality results for their patients and institutions,” said Craig Howell, SVP for Marketing of Seegene USA, Inc. “As well, we believe our ongoing IVD assay development requires custom control and validation panel expertise that is met by Microbix’s competencies.”
