Presence of HCV E2 peptide-specific antibodies in HCIGIV. (A) Determination of HCIGIV antibody titer to peptide A. The x axis indicates the dilution of HCIGIV, and the y axis indicates absorbance at 450 nm in ELISA. Albumin (5%) and a control IGIV (5%) at 1:400 dilution in PBS were used as controls. (B) Spiking of HCIGIV into the control IGIV. The x axis indicates dilution of HCIGIV in the control IGIV. HCIGIV at 1:400 dilution alone was used as the positive control. Albumin (5%) and the control IGIV (5%) at 1:400 dilution were used as negative controls. The y axis indicates absorbance at 450 nm in ELISA.
