| Research Abstract |
In this study, first, bioluminescence resonance energy transfer (BRET) based Ca^<2+> indicator, BRAC was developed and tested to evaluate its physiochemical properties. Second, BRAC was used to visualize Ca^<2+> dynamics in living cells (HeLa cells) and living plant (Arabidopsis thaliana) leaf. Finally, to make the indicator based on bioluminescent-fluorescent double resonant energy transfer, appropriate FRET acceptor for FRET donor Venus were investigated in possible orange to red fluorescent protein candidates. However FRET efficiency between Venus and these orange to red fluorescent proteins were poor, so additional studies should be needed.
