Coelenterazine h (2-Deoxycoelenterazine), a coelenterazine derivative, is a luminescent substrate for RLuc8. Coelenterazine h is more sensitive to Ca2+, thus providing a valuable tool for measuring small changes in Ca2+ concentrations[1][2][3][4].
Coelenterazine h (1-10 μM) can be used as the luminescent substrate for RLuc8[4].
In the measurements of Ca2+ binding kinetics of BRAC, emission intensity of Venus (530 nm) from BRAC are monitored at 1 kHz just after rapid mixing of 5 nM BRAC protein with 20 μM coelenterazine-h in various concentration of Ca2+ buffer[4].
