Impressive Results Across Multiple Proteins

The research team, led by Kaiyi Jiang, Zhaoqing Yan, and Matteo Di Bernardo, demonstrated EVOLVEpro's effectiveness by engineering six different proteins:

1. Monoclonal antibodies: Up to 30-fold improvement in target binding
2. Miniature CRISPR nuclease: 5 times more effective at genetic modifications
3. Prime editor: Doubled efficiency in genome sequence insertion
4. Bxb1 integrase: 4 times more efficient in DNA insertion
5. T7 RNA polymerase: 100 times better at accurate RNA replication 1
