Antibody De Novo Design

Genetic engineering drugs, antibody engineering drugs, blood products drugs, and vaccines are common biological drugs. De novo design of antibodies binding specific epitopes could greatly accelerate discovery of therapeutics as compared to conventional immunization or synthetic library selection strategies. Computational approaches have the potential to dramatically reduce the resources required for antibody discovery while increasing success rates for challenging targets. Our AI-driven platform utilizes molecular simulation technologies to provide antibody De novo design.

Advantages

Powerful drug-like antibody bio-computation (cloud/super-computing).
Modular antibody parts (MAPs) database.
Potent software platforms.
Therapeutic antibodies validation platform.

Why choose us?

  • Experimental methods for the generation of therapeutic antibodies remain time consuming and cannot target a specific antigen epitope. Based on a computational framework, our team has combined AI methods to de novo design antibodies, and facilitate the development of “biologically superior” antibody drugs.
  • We can help our customers effectively reduce the total cost of antibody R&D to effectively shorten the project cycle, especially in the aspects of antibodies humanization, affinity maturation, full human antibody library design.
