Description :Rabbit Polyclonal Antibody

Species :

Tag :

Expression System:

Sequence :

Specificity :Recognizes the mGLUR5 protein

Cited Applications :WB, IHC

Cross Reactivity :Human, Mouse and Rat

Host / Isotype / Clone# :Rabbit, IgG

Immunogen :Peptide from the C-terminal region of rat mGLUR5 and rat mGLUR1a.

Purification :Affinity chromatography

Stability :Store at 4oC (add 0.1% NaN3) for several months, and at -20oC for longer periods. For optimal storage, aliquot target into smaller quantities after centrifugation and store at recommended temperature. For most favorable performance, avoid repeated handling and multiple freeze/thaw cycles.

Sample Data :Western blot of 10 ug of HEK 293 cells expressing mGLUR1a and mGLUR5 showing the specific immunolabeling of the ~125k monomer and the ~250k dimers of mGLUR1a and mGLUR5.

Scientific Background :The metabotropic glutamate receptors (mGLURs) are key receptors in the modulation of excitatory synaptic transmission in the central nervous system. They are implicated in many forms of neural plasticity as well as learning and memory and drug abuse (1). Group I metabotropic glutamate receptors (consisting of mGLUR1 and mGLUR5) are G-protein-coupled neurotransmitter receptors that are localized in the perisynaptic region of the postsynaptic membrane. When activated, Group I mGLURs lead to stimulation of phospholipase and activation of Protein Kinase C. In contrast, activation of Group II metabotropic receptors (mGLUR2 and mGLUR3) leads to inhibition of adenylate cyclase. The mGLUR1 receptor may also be critically involved in limiting the deleterious effects of excitotoxicity (2). In contrast, the mGLUR5 receptor appears to be essential for late phase LTP in area CA1 of the hippocampus (3).
