Antibody Modeling

Discovery Studio delivers the most complete solution for antibody design and optimization. Construct a modeling framework for antibodies, predict antibody physical properties and optimize both pH or thermal stability and formulation developability.

Antibody modeling capabilities include:

  • Automated modeling cascade to easily generate high quality 3D antibody full-length, bispecific, Fab or Fv models from a set of light and heavy antibody chain sequences
  • Simultaneously and independently perform multiple sequence alignments of heavy and light chains
  • Identify antibody template structures
  • Filter templates by canonical structures
  • Build high quality Homology models
  • Graft Fab models onto a full-length template
  • Use standard CDR loop definitions: IMGT, Chotia, Honegger, Kabat
  • Refine CDR loops using either template, loop grafting or ab initio loop modeling
  • Enhanced De Novo Loop prediction
  • Refine residue side chains
  • Perform detailed model analysis
  • Predict protein ionization and residue pKs
  • Protonate residues at a given pH, based on predicted pKs
  • Calculate the total protein charge as a function of pH
  • Predict the isoelectric point (pI)
  • Conduct Thermal or pH-based mutational stability predictions
  • Identify stable disulfide bridge locations
  • Perform antigen-antibody docking using ZDOCK
  • Identify critical interacting residues
  • Perform either implicit solvent-based or explicit solvent-based Molecular Dynamics (MD) simulations using CHARMm c41b1
  • Calculate Temperature- or pH-based mutational binding affinity prediction
  • Calculate aggregation propensity
  • Calculate the Developability Index of IgG1 antibodies
  • Calculate mean atomic charges, average dipole moment, net charge, electrostatic contribution to the solvation energy as a function of pH
  • Predict sites prone to Post Translational Modifications (PTMs) using sequence-based motif searching
