Suppression of mGluRs activated by glutamate application

Name: Sergiy Sylantyev

Species: Human

Cell Line/Tissue: Stem cell - derived neurons

(RS)-MCPG was in use to prevent contamination of NMDA-receptor – generated response to prolonged application of glutamate with (possible) impact from metabotropic glutamate receptors (mGluRs). APV, applied after glutamate and glycine, fully suppressed NMDA-receptor response, thus suggesting no input from mGluRs (see illustration). MCPG works as expected, but takes quite a long time to dissolve for stock preparation.
