Description:

Luciferase catalyzes the substrate luciferin in the presence of Mg2+ and ATP, resulting in a flash of light that decays rapidly. This light can be detected by a luminometer. Luciferase from the firefly has become one of the more widely used reporter proteins for both in vitro and in vivo studies, such as, gene transcription activity assay, the noninvasive imaging of reporter gene expression, imaging cerebral strokes, and tracking genetically engineered T cells. Luciferase/tdTomato dual-reporter HEK293 (HEK293-Luc-RFP) cell line is derived from HEK293 cells by transduction of ALSTEM’s pLenti-SFFV-Luciferase-PGK-tdTomator-T2A-PURO Lentiviral Reporter (cat# LV452) lentivirus, which contains Firefly luciferase encoding gene driven by SFFV promoter, followed by tdTomato and puromycin resistance gene by PGK promoter. This cell line stably expresses luciferase at high level. It also expresses a red fluorescent protein (tdTomato) and is resistant to puromycin. This cell line will be a very useful cell line for non-invasive visualization in both in vitro and in vivo experiments.

Figure 1. Panel A: RFP Fluorescence. Dual-labeled HEK293 cell line expressing tdTomato at 90% cell confluence. The image was taken using a Nikon fluorescent microscope. Panel B: Luciferase activity. Serial dilutions of dual-labeled HEK293 cells were plated into a 96-well plate. The luciferase activity was tested 6 hrs later. Data are expressed as mean /- SD from duplicates of three independent experiments.
