FIG. 1

(a) Uptake of cholera toxin and transferrin into control and nystatin-treated NIH 3T3 cells. NIH 3T3 cells were either mock treated (A and B) or pretreated with nystatin (C to F) and then incubated with either FITC-Ctx (A to D) or OG-Tfrn (E and F). Uptake of FITC-Ctx is shown in panels B and D, and the corresponding α-caveolin-1 uptake is shown in panels A and C. Uptake of OG-Tfrn is shown in panel F, and the corresponding α-clathrin light-chain uptake is shown in panel E. (b) Uptake of cholera toxin and transferrin into control and nystatin-treated BMK cells. BMK cells were either mock treated (A and B) or pretreated with nystatin (C to F) and then incubated with either FITC-Ctx (A to D) or OG-Tfrn (E and F). Uptake of FITC-Ctx is shown in panels B and D, and the corresponding α-caveolin-1 uptake is shown in panels A and C. Uptake of OG-Tfrn is shown in panel F, and the corresponding α-clathrin light-chain uptake is shown in panel E.
