Renilla Luciferase Reporter Lentivirus

Background

Reliable reporter assays depend on internal controls that correct for differences in cell number, transduction efficiency, and assay handling. Renilla luciferase, an enzyme from the sea pansy Renilla reniformis, is widely used for this purpose because it uses a different substrate, coelenterazine, than firefly luciferase and can therefore be measured independently in dual-luciferase formats. When Renilla luciferase is expressed from a constitutive minimal promoter, its signal is largely independent of the pathway under study, providing a normalization baseline. Pairing an experimental firefly or fluorescent reporter with a Renilla luciferase control improves the accuracy and reproducibility of transcriptional activity measurements.

Product Description & Applications

The Renilla Luciferase Reporter Lentivirus is a control lentivirus intended for use as an internal normalization reference alongside other reporter lentivirus products. The construct is an empty vector carrying minimal TATA-box-driven Renilla luciferase as the reporter, providing a stable, pathway-independent signal. Drug-selection markers (puromycin or blasticidin) are driven separately by an EF1a promoter, enabling straightforward establishment of stable cell lines. Co-transducing cells with this control and an experimental reporter allows normalization of reporter readouts for transduction efficiency and cell number, improving assay accuracy and reproducibility. Supplied as lentiviral particles purified by PEG precipitation and sucrose gradient centrifugation, it efficiently transduces difficult-to-transfect cells, including primary and thawed cells.

About This Product

This reporter lentivirus places a EGFP, mCherry, Renilla Luc, GFP, RFP, Luc reporter gene under the control of tandem consensus response elements specific for the Internal Ctrl transcription factor, coupled to a minimal TATA-box promoter and a proprietary upstream enhancer that maximizes signal-to-noise. The constitutively expressed selection marker (Puromycin, Blasticidin) and/or secondary reporter enables stable polyclonal cell line generation and flexible readout by fluorescence microscopy, flow cytometry, or luminometry.

Stable integration via the lentiviral backbone ensures consistent, clonally representative reporter expression in dividing and post-mitotic target cells — including primary T cells, macrophages, organoids, and cryopreserved material — eliminating the variability inherent to transient transfection. The self-inactivating LTR design and third-generation packaging minimize insertional mutagenesis risk and ensure biosafety classification at BSL-2.
