Nf κb luciferase reporter

Manufactured by Promega
Sourced in United States

The NF-κB luciferase reporter is a laboratory tool used to measure the activity of the NF-κB transcription factor. It consists of a reporter gene, the luciferase gene, under the control of an NF-κB responsive promoter. When NF-κB is activated, it binds to the promoter and induces the expression of the luciferase gene, which can then be detected and quantified.

NF-κB Activation Assay in ATDC5 Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
Luciferase assay was performed in ATDC5 cells using an NF-κB Luciferase Reporter (Promega, USA). ATDC5 cells were plated at 25% confluence in 24-well tissue culture plates and NF-κB Luciferase Reporter (50 ng), GPR4 plasmid (500 ng), or vector (pcDNA3.1) were co-transfected with Renilla plasmid (10 ng) on the next day. Twenty-four hours after transfection, the cells were treated with IL-1β (1 ng/ml), with or without 10 μM NE52-QQ57 for 24 h. Then cells were harvested and luciferase activity was assessed with the Dual-Luciferase Reporter Assay System (Promega, USA).

Molecular Cloning for LOXL1-AS1 Regulation

Check if the same lab product or an alternative is used in the 5 most similar protocols
A fragment expressing LOXL1-AS1 was cloned to the pcDNA3.1(+) vector. The miR-708-5p and miR-101-3p expression plasmids were generated by cloning their precursor sequences to pSuper vector. The short hairpin RNA (shRNAs) targeting LOXL1-AS1 or nonspecific control shRNAs were inserted to the pLKO.1 vector. For generation of the LOXL1-AS1 luciferase reporter, the fragment encoding LOXL1-AS1 was cloned downstream of the pGL3 firefly luciferase coding sequence. To disrupt the potential miR-708-5p target site in LOXL1-AS1, site-directed mutagenesis was performed using a site-directed mutagenesis kit (New England Biolabs, Ipswich, MA, USA). An NF-κB luciferase reporter was purchased from Promega (Madison, WI, USA).

Luciferase Assay for NF-κB Regulation

Check if the same lab product or an alternative is used in the 5 most similar protocols
The day before transfection, HSCs were inoculated into a 96-well plate at a density of 5 × 103 cells/well. Following the instructions of the Lipo2000 kit, NF-κB luciferase reporter (20 ng) (Promega Corp., Madison, WI, United States) and pRL-TK (5 ng) (Promega Corp., Madison, WI, United States) were co-transfected with shPEG3 or miR-129-5p mimic into HSCs, and the luciferase activity was determined.

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.
