hERG - Stable Recordings with Accurate Pharmacology

Syncro hERG 2icon sp96   SyncroPatch 384PE data and applications: 
Cells were kindly provided by Charles River Laboratories.

Current-voltage relationship of hERG (Kv11.1) expressed in HEK293 is shown along with pharmacology of 4 hERG-active compounds. The current-voltage relationships for all 384 wells (top) using perforated patch (Escin) and multi-hole chips (4 holes per well) are shown. In all 384 wells, a hERG-mediated current was observed with peak amplitude >700 pA at -20 mV. Using a pharmacology voltage protocol, experiments were stable lasting over 20 minutes. Concentration response curves for astemizole, pimozide, cisapride and terfenadine revealed IC50 values consistent with those found in the literature.

Cells were kindly provided by Charles River.

Screenshots of the PatchControl 384 software showing hCaV1.2β2/α2δ1 current traces in response to a voltage step protocol and the corresponing current-voltage relationship plot. Measured on the SyncroPatch 384PE using perforated patch methodology (Escin) and multi-hole chips (4 holes per well), the success rate of valuable data for the analysis was 100 %. The cells were used from a frozen cell stock (after induction) and recorded stably for more than 20 minutes. The IC50 value of Nifedipine was determined as 21 nM.

KV1.5 - Dose response curve of 4-AP

Cells were kindly provided by Charles River.

Screenshots of the PatchControl 384 software showing a dose-response curve of 4-AP on KV1.5 stably transfected cells. Measured on the SyncroPatch 384PE using multi-hole chips (4 holes per well), the success rate of valuable data for the analysis was 100%. The IC50 value of 160 µM measured on the SyncroPatch 384PE corresponds well to literature (IC50 4-AP: 270 µM; Gutman et al., Pharmacological Reviews 57: 473-508, 2005). 

KV4.3/KChIP2 - Dose-response curve

Cells were kindly provided by Charles River.

Screenshots of the PatchControl 384 software showing KV4.3/KChIP2 current traces in response to a voltage step protocol and the corresponing current-voltage relationship plot. Using whole cell mode in combination with multi-hole chips (4 holes per well), stably transfected cells were measured on the SyncroPatch 384PE. The IC50 value of flecanaide was determined as 28.3 µM which is in accordance to literature. The success rate of valuable data for the analysis was 100%.
