Transport of ¹²⁵I-EM-1 and ¹²⁵I-lactalbumin from the basolateral to apical direction on mouse endothelial cells grown on collagen-coated transwell. In some experiments, unlabeled EM-1 or EM-2 (100 ng/ml or 1,000 ng/ml) was added to the transport buffer. This resulted in significant self-inhibition characteristic of a saturable system. Each data point represents the mean ± SEM of three determinations
