IFN-γ-positive spots in the AST cell population and whole T cell population from the HLA-A2-positive patient with hepatitis B. (a) The IFN-γ-positive spots in the AST cells from ten HLA-A2-positive patients as detected by the AAPC-microplate with PHA stimulation. (b) The IFN-γ-positive spots in the T cells from five HLA-A2-positive patients as detected by the traditional ELISPOT assay with PHA stimulation.
