Representative immunoblots of co-immunoprecipited PICK1:GluA2 from spinal cord lumbar tract total lysates demonstrate partial disruption of this interaction 1 hour after 20 µM i.t. injection of Tat-P4-(C5)2. Densitometric analysis of immunoblots indicate a significant effect following Tat-P4-(C5)2 treatment, graph show mean +/- SEM and individual points, unpaired t-test, **p≤0.01, n=4/group
