Determination of HCV epitope-specific antibodies in HCIGIV. The x axis indicates Ig eluates (AE, BE, CE, DE, or NE) collected after affinity binding and elution of HCIGIV by using a given peptide (peptide A, B, C, D, or N). 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, representing specific binding of a given Ig eluate to each individual peptide.
