what is chemiluminescence
What is chemiluminescence?
  • Occurs when an EXOTHERMIC CHEMICAL reaction releases energy to generate electromagnetic radiation which gives off light1,2
  • Types1:
    • Reactions with synthetic compounds (i.e. H2O2)
    • Bioluminescent reactions – from a living organism
    • Electrochemiluminescent reactions – use electric current

More on Chemiluminescence



See energy gain through chemical reaction

Lower signal (intensity), but little to NO background = beter S/N

  • Light must be absorbed by fluorophore to reach excited state
  • Brighter, but MORE background

(Figure 1) Citation 2

what is bioluminescence
What is bioluminescence?
  • A type of chemiluminescencethat occurs in living organisms
  • Enzyme catalyzed reactions
    • Enzymes: luciferases
      • Firefly luciferase
      • Renilla luciferase (sea pansy)
      • Aequorin (jellyfish- Aequorea victoria)
    • Substrates (photon-emitting): luciferins

Firefly Bioluminescence
  • Light Intensity ~ Chemical Concentration
    • [Chemical] of interest can be ATP, luciferin, or luciferase (hold all others constant)
    • Very large linear range
  • Most common luciferase used in the development of High-Throughput Screening (HTS) Assays

hts luciferase concentration
HTS: Luciferase Concentration
  • Goal: investigate intracellular events by monitoring gene transcription
  • May include internal control (dual-luciferase assay)
  • Simple and efficient (HTS)
  • Commonly used for GPCR and nuclear receptor assays

(Figure 3) Citation 2

hts luciferin concentration
HTS: Luciferin Concentration
  • Luciferin is not naturally linked to physiology (vs. ATP)
  • Use a Pro-luciferin
    • Enzyme of interest must convert this to luciferin link luminescent signal to enzyme of interest

(Figure 3) Citation 2

hts atp concentration
HTS: ATP Concentration
  • Enzyme must be consistent!  Often use “stabilized” luciferase enzymes for HTS
  • Used in:
    • Cytotoxicity screens  ATP concentrations ~ cell viability
    • Kinase activity screens  all kinases consume ATP in phosphorylation rxn
    • Real-time detection of ATPase activity4
    • ~ 100X more sensitive and significantly faster than some dye assays used to look at cell metabolism

(Figure 3) Citation 2

examples of hts assays
Examples of HTS assays
  • Luciferase Enzymatic Activity monitoring assays2
    • Sensitive & broad detection range
  • Protein- Protein interaction assays5,6
    • BRET – Bioluminescence resonance energy transfer
    • PCA – Protein fragment complementation assay
  • Real-time bioluminescence to analyze inhibitors of polymerases (DNA & RNA)7

(Figure 2) Citation 6

examples of hts assays15
Examples of HTS assays
  • BL/CL recombinant whole-cell biosensors
    • Genetically engineered cells
    • Create a luminescent signal ~ to a specific analyte (analyte should be regulating gene expression)
    • Used for monitoring:
      • Stress, oxidants, metals, xenobiotics, receptor activating molecules, etc.

      • Recombinant firefly luciferase (enzyme)
      • D-luciferin(substrate)

(Mg2+) (luciferase)

Luciferin+ ATP + O2

oxyluciferin + AMP + pyrophosphate + CO2 + light

atp determination kit
ATP Determination Kit
  • Advantages:
    • Very sensitive
    • Detect down to ~ 0.1 picomoles of ATP (must create a standard curve within the desired range)
    • Readily available & affordable
  • Uses:
    • Versatile (can be used to look at ATP production in different enzymatic reactions) – NADPH, ATPase
    • Detect contamination in a range of samples (milk, blood, sludge, etc.)
    • Many others!

we can detect atp so what
We can detect ATP. So what?
  • ATP is required for cellular metabolism9
  • “… each human being recycles the equivalent of his/her own mass of ATP every day.”9
  • Extracellular ATP concentrations are critical in biological receptor response10

Rapid Hygiene Tester (Biothema)
  • Detect ATP (quickly) down to very low detection
    • i.e. ATP in one animal cell (~ 1 pg)
  • Also developed to test AMP as well (bi-product of ATP breakdown)
  • Important in the food production industry, labs, hospitals, etc.

Citation 11

  • Chemiluminescence and Bioluminescence are common, extremely versatile, and useful analytical tools
  • HTS methods are becoming increasingly more dependent upon this “background-free” technique
  • The ATP Detection Assay could have huge implications in pharmacology as it evolves for different types of detection
