D-Luciferin Potassium Salt

D-luciferin is the natural substrate of the enzyme luciferase (Luc) which catalyzes the production of the typical yellow-green light of fireflies. The 560 nm chemiluminescence from this reaction peaks within seconds, with light output that is proportional to luciferase concentration when the substrate luciferin is present in excess. The luciferase (luc) gene is a popular reporter gene for research and agent screening. Chemiluminescent techniques are virtually background-free, making the luc reporter gene ideal for detecting low-level gene expression. In addition to its role as a reporter of gene expression, luciferase is commonly used in an extremely sensitive assay for ATP.

In Vitro
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.
