Fig. 4From: A multiepitope peptide vaccine against HCV stimulates neutralizing humoral and persistent cellular responses in miceMurine cytokine production assay of PBMCs by Elispot in response to HCVp6. In vitro stimulation of cells derived from mice immunized with 800 ng (a), 1600 ng (b) and 16 μg (c) was performed with sc. HCVp6 immunization. Cells were pooled from 2 to 3 mice from each time point and allowed to react with anti IFN γ Ab followed by blue color development. Blue spots were counted and compared with controls.
