Effects of different eye drops on band density in the MMP-9 immunoassay. The density of the test line was evaluated after application of 10 μl (200 ng/ml) rhMMP-9, followed by 10 μl of each eye drop sample. The two dotted lines represent the average density of the control band (20 µl, 200 ng/ml rhMMP-9) after 10 and 20 min, respectively.
