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
Brain derived neurotrophic factor (BDNF) is a member of the neurotrophin family of growth factors which includes nerve growth factor (NGF), neurotrophin-3 (NT-3) and neurotrophin-4/5 (NT-4/5).
