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.
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.
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).
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.
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.
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).
“As a leading ion channel contract research organization running one of the most comprehensive ranges of ion channel assays, SB Drug Discovery has been impressed with the flexibility and reliability of the SyncroPatch 384PE (a predecessor model of SyncroPatch 384i), enabling development of a range of varied and complex ion channel assay for both high throughput screening and hit-to-lead profiling purposes. The SyncroPatch has proven to be a crucial addition to SB’s ion channel capabilities and in partnership with expert advice from Nanion’s support team has enabled SB to advance its ion channel capabilities to the forefront of ion channel drug discovery research..“
