“The issuance of this patent further solidifies AbCellera’s position as the innovation leader in next-generation antibody discovery. Our patent portfolio includes broad and foundational claims on the use of microfluidics for high-throughput single-cell secretion assays, with application to antibody discovery and clone selection. We continue to invest heavily in innovation that expands and complements our capabilities, opening up new target classes for biologics and accelerating the development of therapies for patients,” said Carl Hansen, AbCellera’s CEO.
AbCellera brings the expertise of its team and the most advanced scientific tools to enable the discovery of better antibody therapies for its partners. At the core of AbCellera’s platform is a screening technology that allows analysis of millions of single B cells per campaign to identify antibodies with rare therapeutic properties. AbCellera’s patent portfolio covers, among other things, assay miniaturization in nanoliter-volume chambers to assess antibodies from single cells in a matter of hours. These include assays such as live-cell binding, specificity, cross-reactivity, affinity, receptor blocking and function, with applications in antibody discovery, antibody engineering, and cell line selection.
Over the past three years, AbCellera has successfully completed more than 40 antibody discovery programs, including partnerships with top-tier global pharmaceutical companies and venture-backed biotech companies. Applying best-in-class technology and custom innovation to each project, AbCellera has enabled programs for various target classes, including difficult multi-pass membrane proteins, and provided its partners with a competitive advantage through superior diversity, throughput, and quality.
