| Description: | At the assay day cells were washed 3× with assay buffer (as described above), 10 μL buffer remained in the wells after washing. 10 μL Ca kit loading buffer (AAT Bioquest; prepared from the kit containing the following components: Component A: Fluo-8 NW dissolved in 200 μL DMSO and 20 μl of this solution are mixed with 10 ml buffer prepared out of component B and C, Component B: 10× Pluronic F127 Plus diluted 1:10 in component C, Component C: HHBS (Hanks with 20 mM Hepes) was added to the cells and the plates were incubated with lid for 60 minutes at room temperature. 20 μl assay buffer containing 60 μM glycine (20 μM final) and 3 μM glutamate (1 μM final) was added to column 1-23, column 24 got assay buffer without glycine/glutamate to serve as negative unstimulated control. Fluorescence (indicating the calcium influx as a result of the NR1/NR2B ion channel activation) was read on the FLIPRtetra device for 60 seconds to monitor the glutamate induced effects. |
