Figure 3. RT–PCR analyses assessed the duration of endostatin or RGDRGD-endostatin mRNA expression in the rabbit cornea. The expression of the human endostatin or RGDRGD-endostatin gene (550 bp) was observed until 5 days after single subconjunctival gene injection, while there was no expression of after vector (V) injection. The results of rabbit GAPDH (465 bp) confirmed the relative amounts and fidelity of the total RNA samples.
