* Emission maxima. † Relative luminescence capacity = total time-integrated emission of aequorin in saturating Ca2+ relative to native aequorin = 1.0. ‡ Relative intensity at 100 nM Ca2+. § Half-rise time = time for the luminescence signal to reach 50% of the maximum after addition of 1 mM Ca2+ to a standard of aequorin reconstituted with the coelenterazine analog of interest. All data are from Cell Calcium (1993) 14:373.
