ChemPartner and Berkeley Lights Take Next Step in B Cell Antibody Discovery Collaboration

SHANGHAI and SOUTH SAN FRANCISCO,Calif.,May 16,2019 -- Shanghai ChemPartner a leading global Contract Research Organization (CRO),along with Berkeley Lights,Inc. (BLI),the leader in digital cell biology,announced today they have taken the next important step in their collaboration. ChemPartner has installed BLI's Beacon® Optofluidic platform and is the first full-service CRO to offer B Cell antibody discovery servicesto its global client base. This new capability enhances ChemPartner's current antibody discovery platform and augments the end-to-end solutions the company offers for clients and partners.

Through the collaboration,and with BLI's support,ChemPartner will combine BLI's antibody discovery workflow for B cells with ChemPartner's assays. The Beacon® platform is capable of automatically screening tens of thousands of plasma B cells or gene-edited cells,which speeds up a traditionally time-consuming,manual process. Cell characterizations are performed on the platform through a variety of serial or multiplexed fluorescence assays to determine antigen-specific binding to membrane-bound targets on live cells,relative affinity,and functional response with reporter cells. Individual cells with the desired characteristics are selected and exported for genomic profiling or further interrogation. The Beacon® platform enables plasma B cell characterization in less than a day.

"The next step of our collaboration builds on a very successful Proof of Concept study that we completed and presented together with BLI at the Antibody Engineering and Therapeutics conference in December",said Wei Tang,CEO of ChemPartner. "We very much look forward to building on the foundation of this relationship to give ChemPartner's diverse global client base access to this state-of-the-art technology in antibody discovery."

"This collaboration has demonstrated the flexibility of the Beacon® platform as we incorporated the ChemPartner assays to further accelerate antibody discovery," said Andy Last,Chief Commercial Officer at Berkeley Lights,Inc. "We look forward to continuing to work with ChemPartner to further deliver efficiencies to their global clients."
