- Ca2+-Activated K+ Channels (17)
- Inward Rectifier K+ Channels (4)
- Voltage-Gated K+ Channels (32)
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
K+ channels are tetrameric integral membrane proteins that form aqueous pores through which K+ can flow, and are found in many organisms. In neurons, K+ channels are involved in maintaining the resting potential, repolarizing the membrane after action potentials, and controlling the timing of repetitive firing.
