Shape complementarity in Antibody/Antigen recognition

The interaction between an antibody and an antigen relies on shape complementarity.

To better understand this shape complementarity we would like to print in 3D the solvent accessible surface of the Antibody and of the Antigen, and observe how well they fit.

The example we are taking is the crystal structure of the antibody Fab HyHEL5 in complex with lysozyme, PDB code: 1YQV
