AMPA Receptor (GluA2) - Pharmacology
SyncroPatch 384PE (a predecessor model of SyncroPatch 384) data and applications:
Cells were kindly provided by SB Drug Discovery.
The AMPA receptor (GluA2) was analyzed using different positive and negative allosteric modulators (CNQX, LY404187, LY395153, CP465022, Cyclothiazide). After activating the receptor by application of Glutamate, the modulating compound plus glutamate was applied afterwards. Measured on the SyncroPatch 384PE (a predecessor model of SyncroPatch 384), the whole cell patch methodology and multi-hole chips were used.
The lower images on the left hand side are displaying a screenshot of a current after application of the positive modulator LY404187. The EC50 was determined as 379 nM.
AMPA Receptor (GluA2) - Activation by Glutamate
SyncroPatch 384PE (a predecessor model of SyncroPatch 384) data and applications:
Cells were kindly provided by SB Drug Discovery.
The AMPA receptor (GluA2) was activated using different concentrations of glutamate (1 µM - 100 µM). Measured on the SyncroPatch 384PE (a predecessor model of SyncroPatch 384), the whole cell patch methodology and multi-hole chips were used.
The lower two images are displaying screenshots of single cell currents after repetitive glutamate applications:
Left: The same concentration of Glutamate was applied three times.
Right: Four different Glutamate concentrations were applied in a cumulative manner.
AMPA Receptor (GluA2) - Cumulative Concentration Response
SyncroPatch 384PE (a predecessor model of SyncroPatch 384) data and applications:
Cells were kindly provided by SB Drug Discovery.
The AMPA receptor (GluA2)was activated by increasing concentrations of glutamate on the SyncroPatch 384PE (a predecessor model of SyncroPatch 384). L-glutamate was applied for approximately 500 ms in increasing concentrations (A) and a cumulative concentration response curve for glutamate was constructed for 222 wells (C).
The online analysis values peak amplitude and area under the curve (AUC) are shown versus time in Panel B. The fast activation of GluA2 could be captured at higher concentrations (inset; 1 mM).
AMPA Receptor (GluA2) - Inhibition by CNQX
Patchliner data and applications:
Cells were kindly provided by SB Drug Discovery.
The AMPA receptor (GluA2) was blocked by CNQX on the Patchliner. CNQX was pre-incubated and then co-applied with glutamate. CNQX blocked the GluA2-mediated response in a concentration dependent manner and the potency was dependent on glutamate concentration (left). Exemplar GluA2-mediated responses are shown on the right activated by 100 µM glutamate and inhibited by increasing concentrations of CNQX.
AMPA Receptor (GluA2) - Reproducible Responses
Port-a-Patch data and applications:
Cells were kindly provided by SB Drug Discovery.
GluA2 reproducibly recorded on the Port-a-Patch. L-glutamate was applied for 500 ms and this was repeated six times in the same cell showing reproducible responses.
AMPA Receptor (GluA2) - Fast Perfusion with the Port-a-Patch
Port-a-Patch data and applications:
Cells were kindly provided by SB Drug Discovery.
The AMPA receptor (GluA2) was activated by increasing concentrations of glutamate on the Port-a-Patch. L-glutamate was applied for approximately 500 ms in increasing concentrations (left) and a cumulative concentration response curve for glutamate was constructed for 8 cells (right). The fast activation of GluA2 could be captured at higher concentrations (inset; 1 mM).
