Figure 1. Generation of preS1 specific antibodies from naturally recovered patients.

Figure 1

(A) Schematic overview of the generation of recombinant phage displayed monoclonal antibodies from naturally recovered hepatitis B patients. (B) The results of human serum ELISA with immobilized HBsAg VLPs, recombinant preS1(60), recombinant preS1(108) and the preS1-peptide-KLH conjugate. KLH was used as a control antigen while serum from a vaccinated individual (with the HBsAg S-protein only containing vaccine) was used as a healthy control. The cutoff value is shown in each graph by dotted line (mean + 2 S.D.) of the control samples.
