HUMAN RECOMBINANT MGLUR2 RECEPTOR
MULTISCREEN™ MEMBRANE PREPARATION
1 vial (18.6mg/ml)
Expression vector containing full-length human GRM2 cDNA with FLAG tag sequence at N- terminus
Background: The neurotransmitter L-glutamate interacts with both ionotropic and metabotropic receptors. The metabotropic glutamate receptors (mGluRs), which are G protein-coupled receptors, have been divided into 3 groups on the basis of sequence homology, putative signal transduction mechanisms, and pharmacologic properties. Group II and group III mGluRs are linked to the inhibition of the cyclic AMP cascade, but differ in their agonist selectivity. The mGluR2 is a member of group II metabotropic glutamate receptors.
Application: Radioligand Binding Assay
Figure 1. Saturation binding assay curve: Specific binding obtained with mGluR2 membrane with [3H]LY341495. Scatchard plot showing one binding site. Figure 2. Competition binding assay curve: Dose dependent competition of LY341495 for [3H]LY341495 1nM. Figure 3. Receptor expression on cell surface measured by flow cytometry (FACS) using an anti-FLAG antibody. Thin line: parental cells; thick line: receptor-expressing cells.
