Figure 1. Erythrosine Uptake Analysis.

Figure 1

Uptake of erythrosine by pre-malignant (DOK) and malignant (H357) oral epithelial cells was analyzed at 37°C and 4°C. (A) Drug uptake kinetics of erythrosine in DOK cells at 37°C and 4°C. (B) Drug uptake kinetics of erythrosine in H357 cells at 37°C and 4°C. The values are means of four replicate determinations ± S.E.M. Statistical analysis was done via student's t-test with significance set at P<0.05 (* indicates statistical comparison of 37°C data-points vs. the respective data values of 0 µM erythrosine; # indicates comparison of 4°C data-points vs. the respective data values of 0 µM erythrosine and ** indicates comparison between 37°C data-points and the corresponding 4°C data-points).
