Fig. 1From: Uninterrupted monitoring of drug effects in human-induced pluripotent stem cell-derived cardiomyocytes with bioluminescence Ca2+ microscopyDevelopment of Gamillus based bioluminescent Ca2+ indicators. a Schematic representation of the domain structures of Gamillus-based NL(Ca2+)_variants, b relative brightness of recombinant Gamillus-based NL(Ca2+)_variants made by deleting 8–11 amino acids at the fusion site between the FRET acceptor and the split luciferase light donor, with or without Ca2+. Measurements were performed at least in triplicate, and the averaged data and s.d. are shownBack to article page
