The Thermo Scientific Pierce Cypridina Luciferase Glow Assay Kit provides an extremely bright and stable bioluminescence signal (half-life greater than 1 hour) in the presence of Cypridina luciferase reporters.

Features of the Cypridina Luciferase Glow Assay Kit:

Sensitive—highly sensitive detection of Cypridina luciferase activity
Secreted luciferase—allows real-time assays and kinetic studies without destroying cells
Stable—reagents provide increased signal stability compared to flash assays
Simple—does not require a luminometer with injectors
Compatible—assay reagents compatible with other Cypridina or Vargula luciferases
Automation-friendly—amenable to high throughput assays
Convenient—contains a universal cell lysis buffer and optimized glow assay reagent
Safe—allows one to perform non-radioactive assays

This Pierce Luciferase Glow Assay Kit contains reagents for measuring Cypridina luciferase activity in mammalian cell culture media and lysates. When used with Thermo Scientific Cypridina Luc Vectors, the kit provides an extremely sensitive bioluminescent reporter assay system for secreted or intracellular detection of luciferase activity. The light output generated by the luciferase reaction can be correlated to the amount of luciferase protein produced, which in turn is proportional to the activity of the promoter driving the luciferase expression. The kit can be used to detect the activity of any Cypridina luciferases or derivatives that use Vargulin as a substrate.

Includes:
Cell lysis buffer, reaction buffer and substrate

Requires:
Cypridina luciferase and luminometer or other instrument capable of monitoring luminescence, such as Thermo Scientific Luminoskan Ascent and Varioskan Flash Microplate Readers.

Applications:
• Promoter studies for analyzing cis- regulatory elements and trans-acting factors
• Drug screening
• siRNA and miRNA screening
• Multiplexed assays to study off-target effects
• Secretory pathway/protein localization reporter assays
• Signal transduction pathway analysis
• RNA splicing studies

The Cypridina luciferase is a 61kDa protein from the marine ostracod, Cypridina noctiluca. Cypridina luciferase is highly secreted into the cell culture media, allowing for live cell monitoring of reporter activity. Light output captured using a luminometer can be correlated with the amount of Cypridina luciferase protein produced and used to determine the activity of the promoter driving Cypridina expression. The Cypridina gene in Thermo Scientific Cypridina Luc Vectors is modified for expression in mammalian cells and provides optimal performance with the assay kit. The Cypridina glow reagent yields a Cypridina luciferase reaction with glow-type kinetics and is recommended for luminometers without injectors or for applications requiring batch processing of samples.

Frequently asked questions (FAQs)

I got a high background signal with a Gaussia/Cypridina/Renilla Luciferase Glow/Luciferase Flash assay. What went wrong?

Here are possible causes and solutions:

- Non-specific oxidation of substrate: Use less serum in the cell culture media; Note: Albumin can increase the auto-oxidation of Vargulin; Avoid repeated freezing and thawing of the sample.
- Control sample is contaminated: Use new sample; Change pipette tips after each well.

I am getting a high saturating signal with a Gaussia/Cypridina/Renilla Luciferase Glow/Luciferase Flash assay. What could have happened?

This could be due to high luciferase expression. Here are some suggestions:

  • Reduce incubation time before collecting samples. 
  • Decrease the integration time on the instrument.
  • Dilute the sample: for secreted Gaussia/Cypridina Luciferase, dilute the sample using media from the cell culture; for cell lysate, dilute the sample using lysis buffer 


  • Note: A low sample volume can increase assay variability. Dilute the sample and use the recommended volume of 10-20 µL per assay.

    Why am I getting a low signal in lysate using a Gaussia/Cypridina/Renilla Luciferase Glow/Luciferase Flash assay? Can you provide some suggestions?

    Here are possible causes and solutions:

    - Non-optimized lysis buffer used: Assay luciferase activity in the media to confirm good expression of luciferase; Use only the provided lysis buffer.
    - Low luciferase expression: Lyse cells in smaller volume of 1X Cell Lysis Buffer; Use a different promoter or growth conditions to improve expression; Increase the integration time on the instrument; Scale up volume of sample and reagent per well.

    I got a low signal in media when I used a Gaussia/Cypridina/Renilla Luciferase Glow/Luciferase Flash assay. What happened?

    Here are possible causes and solutions:

    - Insufficient luciferase accumulation in media: Incubate cells for a longer time.
    - Low luciferase expression: Use less media per well during the experiment;.Use a different promoter or growth conditions to improve expression;.Increase the integration time on the instrument;.Scale-up the volume of sample and reagent per well.
    - Treatment interfered with cellular secretory pathway: Transfect cells with a plasmid for constitutive expression of Luciferase (i.e., with pTK or pCMV promoter); Determine if luciferase actively expresses in media without treatment. Add treatment; Determine if there is a corresponding drop in luciferase activity from the constitutively expressed plasmid.

    I am getting no signal with my Gaussia/Cypridina/Renilla Luciferase Glow/Luciferase Flash assay. Why is this?

    Here are possible causes and solutions:

    - Low transfection efficiency: Optimize transfection conditions using a visual transfection control (e.g., a plasmid over-expressing a fluorescent protein); Verify plasmid DNA quality - use only transfection grade DNA; Use actively dividing, low passage cells; Use a different cell type.
    - No or low promoter activity: Use conditions known for promoter activation; Incubate cells for a longer time; Change growth conditions to improve expression; Use a different promoter.
    - Substrate auto-oxidized: Protect substrate from light and air; Maintain 100X Coelenterazine at -80 degrees C; maintain 100X Vargulin at -80 degrees C; Prepare new Coelenterazine Working Solution if used longer than 8 hours; Prepare new Vargulin Working Solution if used longer than 2 hours
