Figure 1From: Ultrasound-targeted microbubble destruction mediated herpes simplex virus-thymidine kinase gene treats hepatoma in miceThe expression of TK protein was detected by Western-blot 48 h after transfection. Each group has a single band at 25 kDa and the TK protein expression was the highest in the HSV-TK+ US+MB group (A. PBS group; B. HSV-TK; C. HSV-TK+US; D. HSV-TK+US+MB).Back to article page
