Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.

Mechanism of Action

In vitro

1.Example protocol for in vitro bioluminescent image assays
a) Prepare a 100 mM (100-200X) Luciferin stock solution in sterile water. Mix well. Use immediately, or make single use aliquots, and store at -20℃, avoid freeze-thaw cycles, avoid exposure to the light.
b) Prepare a 0.5-1 mM working solution of D-Luciferin in pre-warmed tissue culture medium.
c) Aspirate media from cultured cells.
d) Add Luciferin working solution to cells, and incubate the cells for 5-10 minutes at 37℃ just prior to imaging.
2.Example protocol for in vivo bioluminescent image assays
a) Prepare a 15 mg/mL Luciferin stock solution in DPBS, without Mg2+ and Ca2+. Mix well.
b) Filter sterilizes the solution through a 0.2 μm filter. Use immediately, or make single use aliquots, and store at -20℃, avoid freeze-thaw cycles, avoid exposure to the light.
c) Inject the luciferin intra-peritoneally (i.p.) 10-15 minutes before imaging at 150 mg/kg (or 10 μL/g of luciferin stock solution) of the animal body weight.
Note: A kinetic study of luciferin should be performed for each animal model to determine peak signal time.
3.Example protocol for luciferin reporter assays
a) Prepare a 100 mM Luciferin stock solution in sterile water. Use immediately, or make single use aliquots, and store at -20℃, avoid freeze-thaw cycles, avoid exposure to the light.
b) Prepare a 1 mM working solution of D-Luciferin with 3 mM ATP, 1 mM DTT and 15 mM MgSO4 in 25 mM tricine buffer pH 7.8.
c) Pipette 5-10 μLof cell lysate into a microplate. Use lysis reagent or buffer without lysate as a blank.
d) Prime luminometer with luciferin working solution.
e) Inject 200 μL of luciferin working solution with no delay and a 10 second integration time.
