Figure 2. The sequence analysis of the endostatin and modified RGDRGD-endostatin genes. A: The sequence analysis of the endostatin gene in the range of 70 to 100 bp. B: The sequence analysis of the modified RGDRGD-endostatin gene in the range of 70 to 97 bp. The sequence analysis indicated that a modified endostatin gene was obtained by delete alanine ala (A) and isoleucine ile (I) changed to asparticacid asp (D), and that the RGDRGD motif was successfully constructed.
