The NMDA receptors are members of the glutamate receptor family of ion channels that also include the AMPA and Kainate receptors.
The NMDA receptors are encoded by seven genes: one NMDAR1 (or NR1) subunit, four NR2 (NR2A-NR2D) and two NR3 (NR3A-NR3B) subunits. The functional NMDA receptor appears to be a heterotetramer composed of two NMDAR1 and two NMDAR2 subunits. Whereas the NMDAR2 subunits that assemble with the NMDAR1 subunit can be either of the same kind (i.e. two NMDAR2A subunits) or different (one NMDAR2A with one NMDAR2B). NMDAR3 subunits can substitute the NMDAR2 subunits in their complex with the NMDAR1 subunit.
NMDAR is unique among ligand-gated ion channels in that it requires the simultaneous binding of two obligatory agonists: glycine and glutamate that bind to the NMDAR1 and NMDAR2 binding sites respectively. Another unique characteristic of the NMDA receptors is their dependence on membrane potential. At resting membrane potentials the channels are blocked by extracellular Mg2+. Neuronal depolarization relieves the Mg2+ blockage and allows ion influx into the cells. NMDA receptors are strongly selective for Ca2+ influx differing from the other glutamate receptor ion channels that are non-selective cation channels.
Ca2+ entry through the NMDAR regulates numerous downstream signaling pathways including long term potentiation (a molecular model of memory) and synaptic plasticity that may underlie learning. In addition, the NMDA receptors have been implicated in a variety of neurological disorders including epilepsy, ischemic brain damage, Parkinson’s and Alzheimer’s disease.
NMDA receptors expression and function are modulated by a variety of factors including receptor trafficking to the synapses and internalization as well as phosphorylation and interaction with other intracellular proteins.
Immuno-colocalization of GluN2A and SynGAP in rat cingulate cortex.Immunohistochemical staining of immersion-fixed, free floating rat brain frozen sections using Anti-NMDAR2A (GluN2A) (extracellular)-ATTO-488 Antibody (#AGC-002-AG), (1:200) and Anti-SynGAP Antibody (#APZ-032), (1:200), followed by donkey-anti-rabbit-Cy3. A. GluN2A staining (green) appears in neuronal profiles (arrows). B. SynGAP staining (red) is detected mostly in apical dendrites (horizontal arrows) and in neuronal soma (vertical arrows). C. Merge of the two images demonstrates colocalization in some neurons (vertical arrows). Cell nuclei are stained with DAPI (blue).
Anti-NMDAR2A (GluN2A) (extracellular) Antibody (#AGC-002) is a highly specific antibody directed against an extracellular epitope of the rat protein. The antibody can be used in western blot, immunoprecipitation, immunocytochemistry, and immunohistochemistry. It has been designed to recognize GluN2A from rat, mouse, and human samples.
Anti-NMDAR2A (GluN2A) (extracellular)-ATTO-488 Antibody (#AGC-002-AG) is directly labeled with an ATTO-488 fluorescent dye. ATTO dyes are characterized by strong absorption (high extinction coefficient), high fluorescence quantum yield, and high photo-stability. The ATTO-488 label is analogous to the well known dye fluorescein isothiocyanate (FITC) and can be used with filters typically used to detect FITC. Anti-NMDAR2A (GluN2A) (extracellular)-ATTO-488 Antibody has been tested in immunohistochemistry and is especially suited for experiments requiring simultaneous labeling of different markers.

比如你用anti-MHC-II，mouse IgG1-FITC，那同型就用非特异性的mouse IgG1-FITC，同样浓度
请问：同型对照应该怎么设？
不买专门的IgG2Bisotypecontrol，而用其他的抗体，
比如mouseanti-humanCD117，Igclass也是IgG2B，可以吗？
阴性对照(Isotype Control)：非特异荧光的强弱取决于抗体浓度、单克隆荧光抗体特异性和纯度，应与试验管抗体相对应。在多色分析时，同型对照应与其它抗体同时使用，以避免补偿造成的误差
血小板体外活化试验：使用正常人活化标本作为阳性质控；使用正常人未活化标本作为阴性质控
血小板自身抗体检测：使用含有已知血小板抗体的血清与血小板孵育，作为阳性质控；使用不含血小板抗体的血清与血小板孵育，作为阴性质控
血小板表面抗原缺失：如巨血小板症血小板表面CD42a/CD42b缺失，血小板无力症血小板表面gpIIb/IIIa，即CD41/CD61缺失或异常。使用正常人标本做阳性对照，抗体的同型对照做阴性对照
