| Background | Hepatitis b virus pre-s region (120-145) is a preS2 peptide that inhibits the binding of single-chain Fv fragment (scFv) or IgG to r-HBsAg. |
| In Vitro | Hepatitis b virus pre-s region (120-145) (0.001-10 μM; 30 min) competitively inhibits the binding of scFv or IgG to r-HBsAg (coated on the ELISA plate) in a dose-dependent manner. |
