Fig. 6. Inhibition of GAG synthesis diminishes binding of ¹²⁵I-GDNF to the surface of RET/GFR1-MDCK cells. The separation between the curves becomes statistically significant above 300 pM: the plotted points are means of triplicate wells, and error bars represent standard deviation; all point have error bars, but some are too small to see behind the squares and triangles themselves.
