Fig. 4. Expression of EGFP-Rab proteins in ashen melanocytes. Melan-ash2 cells were transiently transfected with EGFP-Rab27 (C,D), EGFP-Rab5 (E,F), EGFP-Rab1 (G,H), EGFP-Rab27187/Rab535 (I,J) or EGFP-Rab27187/Rab134 (K,L). A and B show non-transfected cells; A,C,E,G,I,K show EGFP fluorescence, and B,D,F,H,J,L show the corresponding phase-contrast images.
