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
Neuromedin U (NMU) is a highly conserved, ubiquitously distributed neuropeptide, which regulates food intake and body weight. Two high-affinity receptors have been identified for NMU: Neuromedin U receptor 1(NMUR1) and Neuromedin U receptor 2 (NMUR2) that belong to the G-protein coupled receptors (GPCRs). These receptors are members of the rhodopsin-like class A G-protein coupled receptors family and share about 50% identity with each other in the seven transmembrane region.
