Determination of HSV1-TK and HSV1-sr39TK gene expression level in C6 cells by immunocytochemistry 48 hours after addition of DNA-liposome complex (×400). The percentages of TK positive cells in cultured C6-TK (a) and C6-sr39TK cells (b) were and , respectively (). Black arrow indicated immunostaining positive cells.
