Inability of Brilliant Yellow, Direct Violet 51, and XAS 0919 to affect synaptosomal glutamate uptake

Test compounds	Concentration μM	Glutamate uptake dpm	%Control

Direct Violet 51	50	258,020	104

Synaptosomes were incubated with [³H]glutamate in the absence or presence of 50 μM test agent in a Krebs-Ringer solution, as described in Materials and Methods. Na⁺-dependent [³H]glutamate uptake into synaptosomes is presented.
