VICTORIA, October 8, 2020 / – IMMUNOPRECISE ANTIBODIES LTD. (the “Company” or “IPA”) (TSX VENTURE: IPA) (OTCQB: IPATF) (FSE: TQB2), a leader in full-service, therapeutic antibody discovery and development, today announced an update on their NSERC-funded partnership with the University of Victoria for the generation of a real-time cell-phone based COVID-19 antibody diagnostic test.

In May, the Company announced the partnership objective to develop a colorimetric, easy to use, saliva test for the detection and screening of SARS-CoV-2. The test is designed to have a detectable color change that can be easily measured using a cell phone camera and application. The results, including the general location (by zone rather than by specific household, to comply with privacy rights) of the test, can be uploaded to a cloud-hosted database. This will provide immediate information about the number of infections and the general locations to the health authorities.

Dr. Alexandre Brolo’s lab at the University of Victoria has succeeded in optimizing the chemistry to be used in a critical part of the diagnostic application- the consistent modification of strips with nanoparticles that present a distinct color change upon the binding of antibodies to SARS-CoV-2 proteins.

As an additional milestone in the development of the diagnostic, Dr. Brolo’s research team, well known for their historical work in the development of diagnostics for the Zika virus, has designed and 3D-printed a reader prototype enabling the use of the diagnostic application within a standard mobile phone.

As a prototype proof of concept, the research team at the University of Victoria has demonstrated significant and detectable color change when testing the use of the diagnostic with a commercial mobile phone app. The test has been further validated using an assay demonstrating the flow of validated human IgG antibody samples across the surface of the nanoparticle-coated strip containing SARS-CoV-2 antigen.

Antibodies developed for diagnostic purposes require broad epitope coverage, high specificity, low background noise and heightened affinity. Monoclonal antibodies with these characteristics can detect nuanced differences between similar molecules more readily, to avoid false positive results.

The rabbit’s immune system is unique in that it creates highly diverse repertoire of antibodies via its unique gene conversion mechanism and the antibodies themselves have more variation in length and sequence compared to rodents and humans. Rabbit antibodies can identify epitopes on molecules that are non-immunogenic in other species.

The combination of ImmunoPrecise’s B cell Select™ platform and the rabbit’s immune system produces antibodies particularly useful for applications that require extremely low background to allow for the detection and verification of low-level biomarkers with little to no-cross reactivity. IPA has performed over 150 successful diagnostic rabbit B cell programs, many of which have been for point of care lateral flow assays.

“Rabbit monoclonal antibodies developed via our B cell Select™ platform consistently provide panels of highly specific, non-cross-reactive antibodies which are adaptable to any immunodiagnostic format” states Dr. Andra Li, Scientific Director and co-developer of B cell Select™.

Upon successful commercialization of the diagnostic kit, ImmunoPrecise has committed to paying 5% of Global Net Revenue to the University of Victoria.

About Brolo Group
Dr. Alexandre G. Brolo is a professor at the University of Victoria in Canada where he directs an innovative, multidisciplinary and high-impact research program that spans the areas of nanotechnology, surface spectroscopy, electrochemistry and bioanalytical chemistry. Dr. Brolo’s research is centered on the optical and spectroscopic properties of metallic nanostructures that support a physical phenomenon called “surface plasmon excitation”. His work explores the fabrication, characterization, and application of these metallic nanostructures in biosensing and in enhanced spectroscopy, particularly in their use for remote chemical sensing and in combination with microfluidics. Dr. Brolo has published more than 150 research papers in top international journals and conference proceedings and presented on numerous occasions.
