PGK, mammalian promoter

Promoter for expression of genes in mammalian cells

Contribution: NUDT_CHINA 2019

Summary：in this part, we made contributions to the quantitative characterization data of mammalian PGK Promoter. We measured the strength of this promoter by the expression of firefly luciferase reporter gene in HepG2 cells.

Methods

To characterize the PGK promoter, firefly luciferase was used as the reporter gene to quantify the transcriptional strength of promoter. To be specific, plasmids carrying PGK promoter-firefly luciferase cassette was transfected into liver carcinoma cell line HepG2 by lipo3000 under standard proytocol. Cells were cultures under standard DMEM High glucose medium under 5% CO2 and 37 ℃ with 10% FBS. Cells were harvested 0, 6, 12 and 24h after transfection, and firefly luciferase activity was measured by Beyotime™ Dual Luciferase Reporter Gene Assay Kit.

Results

The result showed a significant increase of firefly luciferase within 24 hours of transfection.
