Did you mean the density of metabotropic GluR2 receptor? Or, what is the physiological concentration of excitatory glutamate around glutamatergic neuron? Are GluR2 receptors located on neuronal surface?

I mean to say the concentration of mGluR2 on the surface of Glutamatergic neurons.

The unit of concentration should be mole/volume (e.g., microM/microliter or microM/ml). What is the volume of mGluR2 on neuronal surface membrane? What is the molecular number and molecular weight of mGluR2 receptor?

Hi Dr Wu,

Do you know how many receptors per micrometer square are reported? That is what I am looking for.

Thanks,

Deo
