The Thermo Scientific pCMV-Gaussia-Dura Luc vector is a derivative of pMCS-Gaussia-Dura Luc. It contains a mutant form of the Gaussia luciferase gene (conferring better bioluminescent signal stability than the native luciferase) under the control of the strong Cytomegalovirus (CMV) promoter. This constitutive expression vector can be used as a normalization control to account for experimental variation in combination with other reporters.

Features of the pCMV-Gaussia-Dura Luc vector:

• Strong (CMV) constitutive promoter for co-transfection and normalization
• Naturally-secreting Gaussia-Dura luciferase gene, optimized for high expression and glow-stability in mammalian systems
• Multiple cloning site (MCS) provides versatility for transfer of regulatory elements from one plasmid to another
• Transcription termination site (Ter), Lac operator (Lac O1), and transcriptional pause site (TPS) used to minimize background by reducing transcriptional read-through
• Both puromycin (Pur) and ampicillin (Amp) markers for drug selection in mammalian and bacterial cells, respectively
• High-copy pUC bacterial DNA replication origin

Gaussia-Dura luciferase (approx. 20kDa) is a secreted protein that enables measurement of the reporter activity in media (for real-time assays) and in cell lysates. The parent pMCS vector contains a multiple cloning site for cloning a promoter to study its regulatory potential.

These vectors are subject to a limited use label license.

Frequently asked questions (FAQs)

What options do you offer for luciferase vectors?

There are three vectors available for each expressed luciferase; pMCS, pCMV, and pTK. We recommend using pMCS to measure the activity of the reporter, and pCMV, and pTK as positive control vectors. For high level constitutive expression of Luciferase, we recommend using the CMV (Cytomegalovirus) promoter vector and for low level constitutive expression of luciferase, we recommend using the pTK (thymidine kinase) promoter vector.

What is the stability of the secreted luciferase?

Gaussia, Gaussia-Dura, and Cypridina Luciferase are stable in the culture media for greater than 24 hours. Generally, after transfection of CMV driven constructs, we see ever increasing secreted signal between 24 and 72 hours.

How quickly is luciferase secreted?

The earliest detectable signal will depend on the strength of the promoter. In general, with a strong promoter (such as CMV), significant signal over background can be seen in as little as 20 minutes. However, with a weaker inducible promoter, significant signal over background may take 1-2 hours after induction.

Do you still offer quantitative IP (qIP) Luciferase assay kits?

Our qIP Luciferase assay kits have been discontinued but we do carry epitope-tagged (HA or c-Myc) and Tluc (TurboLuc luciferase)-tagged mammalian expression vectors, and qIP protein interaction assay reagents for these assay kits.
