One glo luciferase assay system

Manufactured by Promega
Sourced in United States, Germany, Sweden

The ONE-Glo Luciferase Assay System is a luminescent reporter assay kit designed for quantitative measurement of firefly luciferase activity in cell-based assays. The assay is based on the luciferase enzyme, which catalyzes the oxidation of luciferin in the presence of ATP, Mg2+, and oxygen, resulting in the emission of light. The ONE-Glo Luciferase Assay System provides a sensitive and robust method for detecting and quantifying luciferase reporter gene expression.

For pseudotyped HIV-1 infection, 2.5 × 105 MM-6 cells were differentiated by 50 nM of PMA for 3 days in 12-well plate. In RNAi experiments, cells were transfected with 300 nM of indicated siRNA by Nucleofector Kit-V and suspended in PMA containing medium. After 3 days, NL4-3 viral solution (p24, 50 ng) was added, and incubated for 2 h. Following washing twice with pre-warmed medium, cells were cultured in PMA containing medium for additional 1 or 2 days, for neutral comet assay or Alu-gag two-step nested qPCR analysis, respectively. For luciferase assay, cell cultures (50,000 cells/well, in 96well plate) at 3 days post-infection (dpi) were directly lysed in equal volume of One-Glo Luciferase assay system (Promega) solution, and relative light units (RLU) were measured by microplate luminometer (Veritas). For FCM analysis of EGFP, cells were fixed with 1% paraformaldehyde at least 30 min at room temperature at 3dpi, and analysed by FACSCalibur on at least 10,000 cells.

Chimeric receptor signaling in Jurkat cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
The mCD28/hCD28 and mCD28/hCD112R chimeras were generated by PCR and cloned into a pcDNA3.1(−) expression vector. We transduced chimera genes into Jurkat cells stably expressing a luciferase reporter under the control of NFAT response element (Jurkat-NFAT-Luc; Promega). Transfectants were selected with Zeocin and further enriched by flow cytometry sorting. Transfected Jurkat cells were stimulated with coated human CD3 mAb (OKT3) for 4 h with or without mouse CD28 mAb (clone 37.51). The presence of mouse CD28 mAb acts as an agonist to amplify signals transduced by the intracellular domain of the chimeras. After stimulation, cells were lysed with the ONE-Glo Luciferase Assay System (Promega) and measured for luminescent signal instantly.

HaCaT, Caco-2, and Jurkat cells were selected for 1 week by culturing in medium containing additional 1.0 μg/mL puromycin. Each cell line was then plated in a 96-well plate (10000 cells/well, 100 μL medium) using FBS-free media and incubated for 24 h to synchronize the cells. Secosteroids at a series of concentrations were added separately to 96-well plate (1.0 μL/well). The final concentration of DMSO was 0.1%. Cells were incubated for another 24 h, and then 100 μL of solution of ONE-Glo luciferase assay system (Promega, Madison, WI) was added to each well. After 5 min reaction at room temperature, the luciferase signal was detected by a BioTek Synergy HT microplate reader (BioTek Instruments, Inc., Winooski, VT, US). All concentrations of secosteroids were tested in triplicate.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
