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

Mas-related G-protein coupled receptor member D (MRGPRD) is expressed in the dorsal root ganglia, specifically in non-peptidergic, small-diameter, IB4+ C-fiber neurons that innervate the outer layers of the mammalian skin. They transmit polymodal nociceptive information from the skin epidermis to the substantia gelatinosa of the spinal cord.
