Beschreibung: The ion channels activated by glutamate that are sensitive to N-methyl-D-aspartate (NMDA) are designated NMDA receptors (NMDAR). The NMDAR plays an essential role in memory, neuronal development and it has also been implicated in several disorders of the central nervous system including Alzheimer’s, epilepsy and ischemic neuronal cell death (Grosshans et al., 2002, Wenthold et al., 2003, Carroll and Zukin, 2002). The NMDA receptor is also one of the principal molecular targets for alcohol in the CNS (Lovinger et al., 1989, Alvestad et al., 2003, Snell et al., 1996). Channels with physiological characteristics are produced when the NR1 subunit is combined with one or more of the NMDAR2 (NR2 A-D) subunits (Ishii et al., 1993). Overexpression of the NR2B-subunit of the NMDA Receptor has been associated with increases in learning and memory while aged, memory impaired animals have deficiencies in NR2B expression (Clayton et al., 2002a, Clayton et al., 2002b). Recent work suggests that phosphorylation of Tyr1472 on NR2B may regulate the functional expression the receptor in LTP and other forms of plasticity (Nakazawa et al., 2001, Roche et al., 2001). Anti-Phospho Tyr1472 NMDA NR2B-Subunit Western blot of rat hippocampal lysate showing specific immunolabeling of the ~180k NR2B subunit of the NMDAR phosphorylated at Tyr1472 (Control). The phosphospecificity of this labeling is shown in the second lane (lambda-phosphatase: (-Ptase). The blot is identical to the control except that it was incubated in (-Ptase (1200 units for 30 min) before being exposed to the phospho-Tyr1472 NMDA NR2B antibody. The immunolabeling is completely eliminated by treatment with (-Ptase.

Spezifität: Specific for the ~180k NMDAR NR2B-subunit protein phosphorylated at Tyr1472 in Western blots. The antibody also labels prote~65k and ~115k. Immunolabeling is completely blocked by blocked by either (-Ptase or by the phosphopeptide used as the antigen but not by the corresponding dephosphopeptide.

Anwendungen

Applikationshinweise: Recommended Dilution: WB: 1:1000 Quality Control: Western blots performed on each lot.

Reinigung: Prepared from rabbit serum by affinity purification via sequential chromatography on phospho- and dephosphopeptide affinity columns.

Lagerung: Store at -20 °C, stable for 1 year

Beschränkungen: Nur für Forschungszwecke einsetzbar
