Summary Introduction

To determine: The information provided by the results of the experiment about the size of gap-junction channels.

Introduction: Gap junctions permit the passage of ions, small molecules and electrical charges between the cytosols of adjacent cells. Adjacent cells share metabolites through gap junctions. Gap junctions are smaller enough to allow the passage of RNA, proteins or polysaccharides. Cells communicating through gap junctions maintain their own distinctive sets of macromolecules. Gap junctions allow the passage of molecules with a mass up to about 1,000 Da.
