Abstract:In MDCK cells, Slo1 channels are mainly expressed at the apical surface. Similarly, transiently transfected MDCK cells target Slo1 channels to their apical surface. To study the role of the microtubules on apical localization of Slo1 channels, we used a viral construct of Slo1 attached to EGFP (Slo1-EGFP) to induce the expression of Slo1. After 72 hrs of infection, cells were either treated with vehicle (control) or with 33 mM nocodazole to disrupt the microtubules. Cells were fixed and immunolabeled with anti… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
