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

The excitatory effects of glutamate (the major excitatory neurotransmitter) are mediated by the activation of ionotropic and metabotropic receptors. These receptors differ in their molecular, biochemical, physiological and pharmacological properties. The ionotropic glutamate receptors are divided into three main categories: AMPA, NMDA (N-methyl-D-aspartate) and Kainate receptors.
