Luciferase activity detection kit

Manufactured by Promega
Sourced in United States

The Luciferase Activity Detection Kit is a laboratory tool designed to measure the activity of luciferase, a bioluminescent protein. The kit provides reagents and protocols to quantify luciferase expression in cell-based assays, allowing researchers to study gene expression, cell signaling, and other biological processes.

5 protocols using luciferase activity detection kit

1

Assessing miR-708-5p Regulation of circ_0009112

Check if the same lab product or an alternative is used in the 5 most similar protocols
Circbank online database was performed to assess the targeting sequence of miR-708-5p in circ_0009112. The wide-type (wt) sequence of circ_0009112 was amplified and sun-cloned into pmirGLO vector (Promega, Madison, WI, United States), and named as wt-circ_0009112. The mutant (mut) circ_0009112 without the binding sites of miR-708-5p in circ_0009112 was synthesized and inserted into pmirGLO vector (Promega), and named as mut-circ_0009112. The built plasmids were transfected into SaOS2 and U2OS cells with miR-708-5p mimic or miR-NC, respectively, with Lipofectamine 2000 (Thermo Fisher). Luciferase activities were determined by luciferase activity detection kit (Promega). Ranilla Luciferase activity served as a control of firefly luciferase activity.

Luciferase Assay of miR-200b Regulation

Check if the same lab product or an alternative is used in the 5 most similar protocols
The CAF-co-cultured cells were inoculated into 96-well plates at 3×104 cells/well. After culturing for 24 hours, luciferase reporter vectors (HMGB3-MT and HMGB3-WT) and miR-200b mimics were co-transfected into the cells. After transfection for 48 hours, the luciferase activity was examined according to the luciferase activity detection kit instructions (Promega, Madison, WI, USA). The luciferase activity = firefly luciferase activity value/renilla luciferase activity value.

Investigating miR-361-3p and Wnt10A Interactions

Check if the same lab product or an alternative is used in the 5 most similar protocols
The relationship between miR-361-3p and Wnt10A is estimated by https://www.ncbi.nlm.nih.gov/nuccore/NM_025216. Untranslated region 3(UTR) sequence of Wnt10A was synthesized and inserted into a pGL3 promoter. The Mutant fraction (Mut) with miR-361-3p mutation binding site was also cloned into Wnt10A 3ʹUTR of pGL3-Promoter. The pGL3-Promoter-wtWnt10A and pGL3-Promoter-mutWnt10A were delivered to Raji cells with miR-361-3p, respectively. Forty-eight hours after transfection, cells were collected and lysed. Then, the luciferase activity was evaluated by using the luciferase activity detection kit (Promega).

Validating PLXNA1-miR-134 Interaction

Check if the same lab product or an alternative is used in the 5 most similar protocols
The relationship between PLXNA1 and miR-134 was predicted using MicroRNA.org, a biological prediction website. The 3′ untranslated region (UTR) sequence of PLXNA1 was synthesized and then inserted into pMIR-reporter (Promega, Madison, WI, USA). Mutant (Mut) fragment with mutated binding sites of miR-134 in the PLXNA1 3’UTR was also cloned into pMIR-reporter. The pMIR-Wt-PLXNA1 and pMIR-Mut-PLXNA1 were respectively co-transfected with miR-134 into HEK-293 T cells (Shanghai Beinuo Biotechnology Co., Ltd., Shanghai, China). At the 48th h after transfection, the cells were collected and lysed. Then luciferase activity was assessed using the luciferase activity detection kit (Promega).

Detecting miR-21-5p Binding to KRIT1 3'UTR

Check if the same lab product or an alternative is used in the 5 most similar protocols
Wild type (WT) and mutant type (MUT) of KRIT1 3'UTR were inserted into pmirGLO plasmid (between NheI and Sal I) to form luciferase vector. Mimics of miR-21-5p (5'-UAGCUUAUCAGACUGAUGUUGA-3') and negative control (NC) mimics (5'-UUCUCCGAACGUGUCACGUTT-3') were used to detect the bind of miR-21-5p to KIRT1 3'UTR. Transfections int HUVECs were performed using Lipofectamine 2000 (Invitrogen, Carlsbad, CA). Luciferase activity of re y was detected with Luciferase Activity Detection Kit (E1910, Promega, USA) using a Chemiluminescence Apparatus (Lumat LB 9507, Berthold, German).

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.
