E4CPG (35 nM/3.5 μL, i.c.v.) completely blocks long-term depression (LTD) induced by the group I mGluR agonist Dihydroxyphenylglycine (DHPG, 100 nM/5 μL, i.c.v.) in male Sprague-Dawley rats[5].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:Male Swiss mice (25-35 g)[4]
-
Dosage:3-30 nmol/site (i.t.), 1-10 μmol/paw (i.pl.) and 1-10 nmol/ site (i.c.v.)
