pCMV-CLuc 2 Control Plasmid

Catalog # N0321 was discontinued on August 02, 2018 ;

The pCMV-CLuc 2 Control Plasmid is a mammalian expression plasmid that constitutively expresses the secreted luciferase from the Ostrapod Cypridina noctiluca (CLuc) under the control of the CMV promoter.

View sequence details
CLuc can be assayed in the culture medium of mammalian cells expressing Cypridina
CLuc does not use the same substrate as other marine luciferases, e.g., Renilla and Gaussia. Therefore, it is possible to assay both CLuc and GLuc independently in cell culture medium from cells expressing both reporters.
Can be used to generate Neomycin-resistant stable cell lines

Product Information
The pCMV-CLuc Control Plasmid is a mammalian expression vector that encodes the secreted luciferase from the Ostracod Cypridina noctiluca as a reporter, under the control of the constitutive CMV (cytomegalovirus) promoter. Cypridina luciferase (CLuc) is a 62 kDa protein with a native signal peptide at the N-terminus that allows it to be secreted from mammalian cells (1). Because it is secreted CLuc can be detected in the culture medium of mammalian cells expressing the reporter gene. A neomycin resistance gene under the control of an SV40 promoter allows selection for stable integration of the plasmid into the mammalian cell genome using G418.

Figure 1: Activity of Cypridina Luciferase in supernatants and lysates from a stable CLuc-expressing cell line
CLuc activity was measured from 20 µl of cell culture supernatant (500 µl total culture volume) and from 20 µl of cell lysate (100 µl total lysate volume).

Figure 2:
The high sensitivity of both the CLuc and GLuc assays allows detection of very small numbers of cells expressing each protein. 20 µl of culture supernatant from the indicated number of cells expressing each reporter were assayed.

DNASU and Addgene are central repositories for plasmid clones and collections that may also be helpful.

  Features
  
  The pCMV-CLuc 2 Control Plasmid can be used as a control for assessing the efficiency of transfection in mammalian cells. Plasmids containing other constitutive promoter elements are also available (see Companion Products Sold Separately).
  
  Application Features
  
  Multiple samples can be obtained from the same transfected cells (i.e., before and after experimental treatments or at multiple time points).
  
  CLuc does not use the same substrate as other marine luciferases (e.g. Renilla, Gaussia). Therefore, it is possible to assay both CLuc and GLuc independently in cell culture medium from cells expressing both reporters (3).
  
  The pCMV-CLuc 2 Control Plasmid can be transfected into cells using any standard transfection protocol.
