Trafficking and internalization of membrane proteins. (a) HeLa cells transiently expressing β1Int-HaloTag were labeled with the HaloTag TMR ligand, then fixed and processed for immunocytochemistry to visualize the endoplasmic reticulum (ER), ER-golgi intermediate complex (ERGIC), or golgi followed by a green secondary antibody. (b) HeLa cells transiently expressing β1Int-HaloTag were labeled with the HaloTag 488 ligand, then fixed and processed for immunocytochemistry to visualize early endosomes (Rab4), late endosomes (Rab11) or cadherin followed by a red secondary antibody. (c) Hela cells transiently expressing β1Int-HaloTag were labeled with the HaloTag 488 ligand and an Alexa Fluor® 594 transferrin conjugate then fixed. Cell images were generated with Olympus FV500 confocal microscope in sequential mode using appropriate filter sets.
