Coelenterazine h
Based on 3 publication(s) in Google Scholar
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 (Ex/Em = 437/466 nm).

Biological Activity
Coelenterazine h (at concentrations of 1-10 μM) can be used as the luminescent substrate for RLuc8 [4].
In the Ca2+ binding kinetics measurement of BRAC, 5 nM BRAC protein was rapidly mixed with 20 μM Coelenterazine h in different concentrations of Ca2+ buffer solution, and the Venus (530 nm) emission intensity of BRAC was monitored at 1 kHz [4].
Guide (The following is our recommended solution. This solution is merely a guideline and should be modified according to your specific needs.)
1. Solution Preparation[4]
1.1 Preparation of Stock Solution
Solvent: Methanol or Ethanol
Concentration: 10 mM (optimized according to the experiment).
1.2 Solution Preparation
Dilute to 10 μM using PBS or cell culture medium (based on experimental optimization).
Note: The raw solution and working solution should be prepared and used immediately. Store them in a dark place.
2. Cell Staining
2.1 Transfect Hela cells with BRAC or G5A.
2.2 Add 10 μM Coelenterazine h to the cell plate.
2.3 Add the dye and the template to the cell culture box and incubate for 1 to 4 hours (depending on the experimental optimization).
2.4 Fluorescence microscopy detection (Ex/Em = 437/466 nm).
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

A. tumefaciens strains carrying NlucN-FLAG, along with avrRpt2-HA-HiBiT or avrPto-HA-HiBiT, were infiltrated into the leaves. Thirty hours after infiltration, leaves discs were collected and incubated with Coelenterazine h (10 µM; 10 min) in a 96-well plate, then the luminescence was monitored using EnSpire Multimode Plate Reader.

Leaves of transgenic A. thaliana plants expressing NlucN were infiltrated with H2O or 1 μM flg22. 24 hours after first infiltration, indicated bacteria (OD600 = 0.1) was infiltrated to the same leaves. Leaf discs were harvested 9 h later, and incubated with Coelenterazine h (10 µM; 10 min) in a 96-well plate, then the luminescence was monitored using EnSpire Multimode Plate Reader.

Effector secretion was induced in vitro. Culture supernatants were collected, incubated with Coelenterazine h (10 μM; 10 min) and NlucN-His, and measured for luminescence. Total protein was analyzed by immunoblot using anti-AvrPto and anti-HA antibodies to detect the accumulation of AvrPto-HiBiT and AvrRpt2-HA-HiBiT. Signal-to-noise ratio was shown.
