↵a Shown is a summary of the 50% inhibitory concentration (IC50) (95% confidence interval [CI]) of purified monoclonal antibodies RG-1, JWW-1, JWW-2, and a negative-control human IgG determined using the FC-PBNA against HPV6/16/26/45/58 pseudovirions using a starting antibody concentration of 200 nM (30 μg/ml). NA, not applicable.
