| | hERG Patch Clamp Assay |
| Description: | All testing was carried out in CHO cells transfected with the hERG gene purchased from Millipore (PrecisION hERG-CHO Recombinant Cell Line CYL3038). The cell line was grown in DMEM/F-12, GlutaMAX with 10% fetal bovine serum, 1% Penicillin-Streptomycin, 1% Geneticin and 1% of 1M HEPES buffer solution, and maintained at approximately 37 °C. in a humidified atmosphere containing 5% carbon dioxide. The cells were passaged every 3-5 days based on confluency. On the day of the experiment, 50%-80% confluent cells were harvested from a 175 cm2 culture flask using Detachin. After 10 minutes of exposure to Detachin at 37 °C., the cells were centrifuged for 1 minute at 1000 RPM. The supernatant was removed and the cell pellet was reconstituted in 5-8 mL of serum free media with 2.5% of 1M HEPES, placed on the Qstirrer, and allowed to recover. After a 30 minute recovery period, experiments were initiated. |
