Serologic Evidence of Frequent Human Infection with WU and KI Polyomaviruses
Figure 3. Effects of preincubation of polyomavirus viral protein 1 on WU ELISA and KI ELISA. Samples were preincubated with single or multiple proteins in different combinations or with the blocking buffer alone. Shown are results of blocking WU ELISA (A) and blocking KI ELISA (B) of representative serum samples. Proteins used in preincubation experiments are indicated by matching color scheme. Blocking data for WU ELISA–negative serum (C05) and KI ELISA–negative serum (C251) are shown for comparison. Toxo Mic, microneme protein from Toxoplasma gondii; SV40, simian virus 40. Error bars indicate mean and SD.
