Berkeley Lights Accelerating Antibody Discovery with Launch of Rabbit Memory B Cell Workflow

Enables access to a broad range of biodiversity to find unique antibodies against challenging targets

MERYVILLE, Calif. — Berkeley Lights, Inc. (NASDAQ: BLI), a leader in digital cell biology, today announced the launch of the Opto® Memory B Discovery Rabbit workflow, expanding the diversity of antibodies customers can discover on the Beacon® platform.

The new workflow enables rapid, automated generation of antigen-specific, functional monoclonal antibodies from rabbit memory B cells, building on prior workflows that used mouse plasma B cell samples. This workflow broadens Berkeley Lights’ market opportunity beyond mouse workflows, enabling discovery of high-value rabbit antibodies that are well-suited for therapeutics, diagnostics and research reagents. While there are currently no robust markers to enrich rabbit plasma B cells, rabbit memory B cells can be readily obtained from blood and easier to source and handle than plasma B cells.

Using the Opto Memory B Discovery Rabbit workflow, Berkeley Lights estimates the Beacon platform can:

  • Screen approximately 15,000 to 60,000 single cells per workflow, depending on chip selection and number of chips used per workflow;
  • Identify hundreds to thousands of antigen-specific hits per workflow; and
  • Recover high-quality antibody sequences for the majority of discovered hits

“We are continuing to advance our workflows in antibody discovery to help our customers find high-value molecules against the most difficult targets,” said Siddhartha Kadia, Ph.D., chief executive officer of Berkeley Lights. “This new workflow targeting rabbit memory B cells expands the diversity of antibodies that our customers can discover on the Beacon platform and offers a superior alternative to traditional methods, which are more costly and time-consuming. Using this technology, our customers will be able to rapidly screen rabbit memory B cells for discovery, recovery, and sequencing of functionally characterized antibodies in just a single week.”
