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
Angiotensins are a family of peptides that are critical players in the control of water and electrolyte balance. Angiotensins mediate their actions via several specific G-protein coupled receptors: AT1, AT2 and MAS Receptors.
