Competitive ELISA assay using 4 healthy controls sera and 8 CHB samples with the highest O.D. out of the 17 ELISA positive sera in Figure 2. Sera were incubated with 10 μg of E1 loop at 37°C for 3 hours, centrifuged and used as the probe in the ELISA experiment. The O.D. of each of the 8 CHB sera decreased by more than half to a value below the cutoff of 0.1 nm.
