Antibody Generation: Single B Cell Cloning vs. Hybridoma

Dr. Andreas Loos

A total of 33,377 plasma cells were screened from PD-L1-immunized mice and the secreted antibodies were tested for binders to PD-L1 and blockers of the interaction between PD-L1 and PD-1. The screening assays were completed and a total of 35 antibodies (BCC-Abs) that bound PD-L1 and blocked the interaction with PD-1 were identified on the day the mice were sacrificed. Single cell sequencing allowed the team to recover 24 paired VH/VL sequences, of which 23 could be expressed and purified.
