Best production cell lines

with >99% monoclonality assurance in just days.

  • The added efficiency and robustness of the Beacon CLD workflow is unparalleled and we look forward to continuing to work with the Berkeley Lights team to bring this exciting technology on board.

Rapid Workflow

 

 

Replace 8-12 weeks of challenging well plate steps with Opto™ CLD on the Beacon® optofluidic system. In Cell Line Development (CLD), you are looking for the rare, high-producing clones. For the greatest genetic diversity, you need to screen thousands of cells. The Opto CLD workflow screens thousands of clones with ease in less than a week.

Complex Antibody Molecules

Select top clones for even non-traditional antibody molecules.

 

 

The Opto CLD Workflow selects top clones by measuring growth and titers over multiple days of on-chip culture. SpotLight™ assays enable quantification of both traditional and non-traditional antibodies, such as Fc-engineered mAbs, bispecifics, and multispecifics.

>99% monoclonality assurance

Get >99% monoclonality assurance with a single, automated round of cloning.

The Berkeley Lights Opto CLD workflow enables in-line controls to measure clonality during clone recovery. After recovery of each clone, media is flushed into “blank” wells to detect any residual cells. Expand >90% of selected clones from the Beacon system when recovered into 96-well plates, with >99% monoclonality assurance –  which is equivalent to four rounds of limiting dilution!

Visual confirmation of monoclonality

Compile a superior data package with simple, visual confirmation of monoclonality

Unlike traditional well-plate approaches, the Opto CLD Workflow provides a visual record of all clones – in an automated fashion – and allows confident assessment of monoclonality. Cells can be visually tracked from the moment they are loaded into NanoPen™ chambers through culture, antibody secretion assays, and eventual recovery of top secreting clones.  Imaging provides information about cell size, morphology, and growth rates for all clones over multiple days of on-chip culture.

Export the best from 1000s of clones

The Opto CLD Workflow enables selection of top clones by measuring growth over multiple days of on-chip culture and secretion titers using quantitative assays for both traditional and non-traditional antibodies.

  • Measure antibody production from 1000s of clones
  • Quantify secretion titers and specific (per-cell) productivity using the Spotlight™ Human Fc and SpotLight™ Human Kappa reagents
  • Enrich and recover top-secreting clones for scale-up

Clones selected based on titer measurements on the Beacon system had 1.5–3-fold higher titers than clones selected using traditional clone picking technology when scaled up to shake flask fed-batch cultures (RIGHT). ©2019 Catalent, Inc.
