The majority of synapses in the central nervous system utilize glutamate as a neurotransmitter to produce rapid neuronal excitation. Glutamate has a diverse array of receptors that can be categorized into two groups: ionotropic and metabotropic. The ionotropic receptors are subdivided into two distint types: 1) receptors for N-methyl D-aspartate (NMDAR) and 2) non-NMDA receptors for AMPA and kainate. Three types of NMDAR2 have been identified: NR2A, NR2B, and NR2C. NR2A and NR2B contain a C-terminal extension (>600 amino acids) that has small scattered regions of conserved sequence. The three NR2 mRNAs show overlapping, differential expression patterns in the rat brain. NR2B has been reported to be expressed in the forebrain, thalamic nuclei, amygdaloid nuclei, caudateputamen, and in restricted regions of the olfactory bulb.

注意事项:
1.Since applications vary, each investigator should titrate the reagent to obtain optimal results.
2.Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing. .
