Luc-Pair Duo-Luciferase HS Assay Kit

Product Description

• High sensitivity of Firefly and Renilla luciferase signals (Figure 1)
• For many different eukaryotic cells (e.g. mammalian, lower invertebrates, etc.) using micro-plates or single-tube luminescence readers
• Very low background luminescence. No subtraction is required from readings
• Quenched Firefly luciferase activity (Figure 2) for quick Glow and Stop-N-Glow two-step assays
• Reliable, linear results for a concentration range over several orders of magnitude
• Compatible with Promega’s Fluc and Rluc vectors

GeneCopoeia’s Luc-Pair™ Duo-Luciferase HS Assay Kit is the perfect choice for high sensitivity detection of Firefly luciferase (FLuc) and Renilla luciferase (Rluc) activities. The Luc-Pair™ Duo-Luciferase HS Assay Kit works great for many different eukaryotic cell types (e.g. mammalian, invertebrates, etc.) using micro-plate or single-tube luminometers, and is compatible with GeneCopoeia, Promega and many other Fluc and Rluc vectors. The Luc-Pair™ Duo-Luciferase HS Assay Kit is ideal for many applications, such as measuring the inhibitory effect of a miRNA on a target sequence.

Performance Data

Figure 1. Activity of Firefly luciferase and Renilla luciferase signals using GeneCopoeia Luc-Pair™ Duo-Luciferase HS Assay Kit. HEK 293 cells were transfected with Promega pGL4.13/pGL4.75 reporter vectors for 48 hours. The FLuc (FLuc-GeneCopoeia) and RLuc (RLuc-GeneCopoeia) activity was measured as described in the procedure. The Promega dual-luciferase assay kit was used (FLuc-Promega and RLuc-Promea) for comparison.

Figure 2. Firefly luciferase activity is quenched with the addition of Luc-H Buffer II. HEK 293 cells were transfected with Promega pGL4.13/pGL4.75 reporter vectors for 48 hours. The firefly luciferase activity was measured as described in the procedure. Next, 1x Luc-H Buffer II (without or with substrate) was added to the wells, followed by count reading in a luminometer. About 99.9% of firefly luciferase activity was quenched (middle column).
