Figure 2From: Papillomavirus pseudovirions packaged with the L2 gene induce cross-neutralizing antibodiesDetection of HPV16, HPV18, HPV31 and HPV58 neutralizing antibodies. The individual mouse neutralizing titers are the means of the last reciprocal dilution providing more than 50% inhibition of luciferase expression. Animals without detectable antibody titers (< 25, dotted line) were assigned a titer of 1 for calculation of GMTs (horizontal bars).Back to article page
