Phage display creates innovative applications to combat hepatitis B virus

Figure 2 Envelope proteins of hepatitis B virus. The translation products of the HBsAg gene are shown as lines of different thickness. Small (S-), middle (M-) and large (L-) HBsAg are translated from a common open reading frame of the HBsAg gene by the use of three in-frame initiation codons (1) at the N-termini of PreS1, PreS2 and S. G: Glycosylation; MYR: Myristic acid; HBV: Hepatitis B virus; HBsAg: Hepatitis B surface antigen.
