Revolutionizing Therapeutic Antibody
Development with Hybridoma Generation

The Powerdoma™ Hybridoma Discovery Platform facilitates high-throughput detection using diverse techniques such as ELISA, FACS, and cell-based mirrorball assays. Consistent positive results are observed across the board, both from the 384-well high-throughput screening and the conventional 96-well screening.

Utilizing hybridoma discovery technology, successful screening of mouse antibodies targeting human proteins was achieved in just 116 days, starting from mouse immunization. From a pool of 19,200 hybridoma clones, 87 cross-positive clones were obtained after examining the cross-reactivity of human and cynomolgus proteins. Of these, 79 clones demonstrated strong binding to the overexpressed cell line. 4 optimal clones were selected for sequencing and recombinant expression, ultimately yielding 3 antibodies exhibiting binding activity.
