“…At an experimental level, temperature control can also be an issue, which is important to study ion channel kinetics of temperature-sensitive variants ( Vandenberg et al, 2006 ; Abdelsayed et al, 2015 ; Lei et al, 2019 ; Jones, 2022 ; Ren et al, 2022 ; Kriegeskorte et al, 2023 ). Whilst temperature can be preset on most APC systems (e.g., Biolin Scientific, Fluxion and Nanion Technologies, Table 1 ), most APC assays for cardiac ion channels have been conducted at room temperature ( Vanoye et al, 2018 ; Glazer et al, 2020b ; Ng et al, 2021 ) due to an inherent instability of cell membranes at physiological temperatures leading to lower success rates.…”
