Figure 4.

Snapshots of the interactions between Ser residues and the PS surface included in the Fab–Fab–on orientation.

Notes: Only the interacting pairs of the amino residue and the ethylbenzene molecule are shown for simplicity. Ser51, Ser64, Ser66, Ser75, and Ser76 in b-region are shown in (A–D), and (D), respectively. Oxygen, nitrogen, carbon, and hydrogen atoms are shown by red, blue, green, and gray colors, respectively.

Abbreviations: Ser, serine; PS, polystyrene; Fab, fragment antigen-binding.
