Figure 5From: Adaptation of an amphibian mucociliary clearance model to evaluate early effects of tobacco smoke exposureA representative gelatinase zymogram on mucus collected from control and cigarette-exposed palates. In the left lane, standards for MMP 2 and 9 are shown. In the next two lanes MMP activity is shown in control mucus (two samples). The next two lanes show MMP activity in two aliquots of the mucus collected from palates exposed to the smoke of four cigarettes.Back to article page
