Binding of HPV58 and HPV59 pentamers to their type-specific neutralizing antibodies, A12A3 and 28F10, respectively. (A and B) Binding profiles of MAbs A12A3 and 28F10 with VLPs or pentamers of HPV58 (A) and HPV59 (B), respectively. (C and D) Neutralization of HPV pseudoviruses of types 58 and 59 by the MAb or Fab fragments of A12A3 (C) and 28F10 (D), respectively. (E and F) Sedimentation coefficient profiles of (E) HPV58 pentamer, A12A3 Fab, and their immune complexes and (F) HPV59 pentamer, 28F10 Fab, and their immune complexes. (G and H) AUC samples of HPV58 (G) and HPV59 (H) assessed by SDS-PAGE.
