The anti-HPV16 L1 IgG titers of mouse sera were measured as described [13] (link), [14] . Briefly, 96-well ELISA plates were coated overnight with 100 ng of purified HPV16 L1 VLPs per well and blocked with 5% skim milk in PBST. The plates were reacted with three- or four-fold serial dilutions of mouse sera for 1 h at 37°C. The anti-HPV16 L1 IgG bound to the coated HPV16 L1 VLPs was detected using HRP-conjugated goat anti-mouse IgG antibody (Bethyl), and color reactions were developed as described above.
