Western blot analysis of extracts from 293T cells, mock transfected (-) or transfected with constructs expressing HA-tagged full-length mouse mGluR2 (mGluR2-HA; +) or HA-tagged full-length mouse mGluR3 (mGluR3-HA; +), using mGluR2 Antibody (upper) or HA-Tag (C29F4) Rabbit mAb #3724 (lower). HA-tagged mGluR cDNAs were a gift from Dr. Gonzalez-Maeso (Mount Sinai School of Medicine, NY).
