AbTherx Partners with Single Cell Technology for First Antibody Discovery Campaigns

Partnership provides AbTherx and licensees of AbTherx’s Atlas™ Mice access to Single Cell Technology’s proprietary single B cell screening engine

Mountain View and San Jose, Calif. – March 13, 2024 – AbTherx, Inc., a biotechnology company with innovative technologies to enable and accelerate antibody discovery, and Single Cell Technology, Inc. (“Single Cell”), a biotechnology company with nine years of experience delivering antibodies to clients across multiple therapeutic areas, today announced that AbTherx selected Single Cell for its first antibody discovery campaigns. As part of this partnership, AbTherx and licensees of AbTherx’s Atlas™ Mice will have access to Single Cell’s proprietary single B cell screening engine.

Single Cell is a leading antibody discovery R&D provider. Its pioneering AbTheneum™ platform compresses campaign timelines and captures all binder and non-binder screening and sequencing data. It screens all antibodies from each cell against multiple parameters while simultaneously sequencing all antibodies on multiple picowell devices. The capture, screen, and sequence workflow takes just three weeks from cells to screened antibody sequences. Since 2015, Single Cell has run a wide range of discovery campaigns, sequencing millions of antibodies.

Atlas™ Mice, a suite of novel transgenic technologies designed for unmatched performance and FTO, were developed by the AbTherx team and are licensed as part of an exclusive partnership with Gilead. Atlas™ Mice are designed to produce robust immune responses, increase hit recovery, enable development of a bispecific antibody format most like native antibodies, and use natural mechanisms to generate long CDR3 antibodies. Committed to making its technologies accessible to all, AbTherx offers flexible partnering models, including options for royalty-free or no upfront fee licensing, that meet the needs of drug developers of all sizes.

“We are excited to combine our novel human Ig transgenic mice with Single Cell’s leading-edge antibody screening engine. This collaboration will allow us to mine a much larger array of B cells from Atlas™ Mice for therapeutic antibodies, compared to other single B cell approaches,” said Peter Brams, PhD, Chief Scientific Officer of AbTherx. “AbTheneum™ uniquely combines biology, miniaturization, and informatics and has been continually refined over many years to allow large-scale screening of single B cells in a smart, flexible, and highly efficient process.”

“We have expanded our capabilities at Single Cell to address antibody developers’ needs, and we are excited to partner our screening engine with AbTherx’s state-of-the-art technologies,” said Chun-Nan Chen, PhD, Chief Executive Officer of Single Cell. We are eager to pair the massive data output and speed of AbTheneum™ with the high-quality performance of Atlas™ Mice to demonstrate how this powerful combination will advance innovative therapeutics.”
