Summary of the phylogeny, tropism, charge and in vitro neutralization by L2 11-88x8 antiserum of the 34 HPV genotypes tested.

Phylogeny and tropism were taken from de Villiers et al [58], predicted net charge of L1 at pH7.4 was calculated as described in [37]. PsVs of each indicated HPV type carrying a luciferase reporter gene were mixed with titrated rabbit L2 α11-88x8 antiserum for two hours at 37°C, then the mixtures were transferred to 293TT cells and cultured for 72 hours. Cells were then lysed and luciferase activity was measured. Neutralization titer and 95% confidence interval are shown.
