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
Nerve growth factor (NGF) is one of the founding and best-characterized member of the neurotrophin family. This family comprises a unique collection of polypeptide growth factors that promote the proliferation, differentiation, survival and death of neuronal and non-neuronal cells.
