VICTORIA, April 17, 2020 /CNW/ – IMMUNOPRECISE ANTIBODIES LTD. (the “Company” or “IPA”) (TSX VENTURE: IPA) (OTC QB: IPATF) is pleased to provide an update on its research activities for the novel coronavirus (SARS-CoV-2) which outlines the Company’s workflows for their experimental vaccines and therapeutics for the research community.

IPA’s multitargeting approach combines various SARS-CoV-2 spike protein forms with the Company’s diverse technologies. Hence, IPA anticipates that it can accelerate anti-SARS-CoV-2 human antibody discovery, targeting multiple viral epitopes and mechanisms of viral evasion, by immunizing Ligand’s (NASDAQ:LGND) OmniRat® animals using the Company’s Rapid Prime protocol followed by IPA’s B cell Select and hybridoma generation in parallel with human, naive phage library screening. Subsequent high-throughput binding assays, computational Artemisoptimization, and protein interaction analyses permit faster preclinical lead selection. 

“In addition to using our antibody discovery platforms for the potentially rapid identification of a diverse panel of fully SARS-CoV-2-specific antibodies, we aim targeting additional novel epitopes which are likely inaccessible to conventional antibody formats by screening our in-house, highly complex, VHH repertoire (collection of variable regions of heavy chain antibodies, a region which binds to the target immunogen),” stated Ilse Roodink, Chairwoman of Talem’s Scientific Advisory Committee and Coronavirus Global Project Leader. “Due to the relative high sequence homology of VHHs with human antibodies, extensive humanization is not required and therefore, our discovery strategy mixture will significantly contribute to the fast generation of a monoclonal antibody cocktail with broad epitope coverage and diverse functionalities, which is key to successful development of an effective, long-lasting therapy with a high safety profile.”

Apart from the various SARS-CoV-2 spike protein forms which IPA has been producing for use in the therapeutic development, data obtained during the discovery and characterization of lead antibody candidates may be of significant value in the reverse-engineering of vaccine candidates used in the formulation of an effective, but low-risk, vaccine.
