Figure 1From: Double suicide genes driven by kinase domain insert containing receptor promoter selectively kill human lung cancer cellsIntrinsic expression of the KDR mRNA and protein. mRNA (A) and protein (B) expression of the KDR was determined by RT-PCR and Western blotting, respectively. There was a significant amount of KDR expression in the NL9980, L9981 and ECV304 cells. The level of KDR expression in the HepG2 cells was not detectable. 1. DL2000 DNA marker; 2. NL9980 cells; 3. L9981 cells; 4. ECV304 cells (positive control); 5. HepG2 cells.Back to article page
