Figure 1From: Enhancement of the expression of HCV core gene does not enhance core-specific immune response in DNA immunization: advantages of the heterologous DNA prime, protein boost immunization regimenExpression of HCV core proteins. Expression of HCV core protein directed by pCMVcore (A), pCMVcoreKozak (B), pCMVcoreIRES (C) in COS-7 cells 72 h post-transfection (Field 1); in BHK-21 cells 48 h (Field 2) and 72 h post transfection (Field 3). Transfection with the recommended amount (lane 1), and two-fold excess of transfection reagent (lane 2).Back to article page
