Witryna4 lis 2024 · Since hERG patch clamp assays are typically run at sub-physiological gating frequencies (and gating is neglected altogether in radio-ligand binding assays), this hijacking effect is likely underestimated to varying degrees (i.e. channel closing likely dominates over the re-solvation costs of the dissociated pore and blocker). WitrynaThe hERG assay is a simple quantitative test that measures the expression of the hERG in various tissues. Its performance has been shown to be highly reproducible across a …
