Figure 2. Rab5 and Rabankyrin5 overexpression increases macropinosome formation.
The distribution of Rab5, Rabankyrin-5 (A) or Rab5(Q79L) (B) in green relative to dextran-positive macropinosomes (red) Scale bar = 10 µm. (C) HEK-Flp-In cells were transiently transfected with pEGFP-C1, pEGFP-Rab5, pEGFP-Rab5-Q79L and pEYFP-Rabankyrin-5. The mean number of macropinosomes/100 transfected cells was quantitated over 3 replicates of 500 transfected cells for each condition. * denotes statistical significance (p<0.05) using the Student's T-test, performing pairwise analyses relative to cells transfected with pEGFP-C1 alone. Error bars denote S.E.M.
