ASAP3-R3 performance in cardiomyocytes. (a) Representative induced pluripotent stem cell derived cardiomyocytes (iPSC-CMs) expressing ASAP3 or ASAP3-R3. Epifluorescence images were acquired using Hamamatsu HCImage software and color channels assigned in NIH Fiji 2.1. (b) Representative single-trial ∆R/R or ∆F/F responses to spontaneous cardiac APs of cells expressing ASAP3, expressing ASAP3-R3, or expressing ASAP3-R3 and treated with isoproterenol (ISO). Graphs were generated in Microsoft Excel for Mac 16. (c) Characterization of traces obtained from ASAP3 (n = 6), ASAP3-R3 (n = 10), or ASAP3-R3 + ISO (n = 7). Graphing and statistical analyses were performed in GraphPad Prism 7.
