FIGURE 9.
Effect of MCab/strep ratio on the cell penetration of strep. A, effect of MCab/Strep-Cy3 ratio on the total entry of Strep-Cy3 in wild-type CHO cells. B, effect of an 8-fold molar excess of non-biotinylated MCa on the penetration of MCab-Strep-Cy3 at a 1:1 molar ratio. C, effect of 5 mm amiloride on Strep-Cy3 entry into wild-type CHO cells as a function of MCab/Strep-Cy3 ratio. Significance is provided as a deviation of 3× the S.D. value from 100% (denoted as asterisks). Strep-Cy3 concentration was kept constant at 1 μm in all experiments. a.u., arbitrary units.
