Extracellular antibodies are ideal research tools for cell-surface proteins.

No permeabilization/fixation because using extracellular antibodies allows you to work with live cells!

Benefits of live cell imaging:
✓ Monitor cell movement
✓ Study protein transport across the cell
✓ Investigate protein internalization

ZAC (zinc-activated channel), which is expressed in human and dog but not in rodents, has been added to the superfamily of ligand-gated ion channels. Like all other ligand-gated ion channels, ZAC has four transmembrane domains and extracellular N- and C-termini. As its name states, the channel is activated by high concentrations of zinc.
