Basic Vector Information

pMIR-Report Luciferase is an essential molecular biology tool plasmid designed for miRNA research. It features a luciferase reporter gene that emits a detectable signal upon expression, allowing for precise quantification of gene expression levels.

The plasmid has a specific region where miRNA binding sites, like the 3′ untranslated region (UTR) of genes such as grouper TRAF6, can be inserted. This enables the investigation of miRNA-target interactions. Compatible with transfection into various cell types, such as grouper spleen (GS) cells, it is used in procedures where the target-containing luciferase plasmids are constructed by cloning UTR fragments into the vector and then cotransfected with miRNAs or controls. The luciferase activity assay measures the impact of miRNAs on target gene expression.

Overall, it plays a crucial role in validating miRNA targets and understanding miRNA-mediated gene regulation, providing valuable insights into biological processes such as immune responses and virus pathogenesis.

Plasmid Protocol

1. Centrifuge at 5,000×g for 5 min.

2. Carefully open the tube and add 20 μl of sterile water to dissolve the DNA.

3. Close the tube and incubate for 10 minutes at room temperature.

4. Briefly vortex the tube and then do a quick spin to concentrate the liquid at the bottom. Speed is less than 5000×g.

5. Store the plasmid at -20 ℃.

6. The concentration of plasmid re-measurement sometimes differs from the nominal value, which may be due to the position of the lyophilized plasmid in the tube, the efficiency of the re-dissolution, the measurement bias, and adsorption on the wall of the tube, therefore, it is recommended to transform and extract the plasmid before using it

General Plasmid Transform Protocol

1. Take one 100μl of the competent cells and thaw it on ice for 10min, add 2μl of plasmid, then ice bath for 30min, then heat-shock it at 42℃ for 60s, do not stir, and then ice bath for 2min.

2. Add 900μl of LB liquid medium without antibiotics, and incubate at 37℃ for 45min (30℃ for 1-1.5 hours) with 180rpm shaking.

3. Centrifuge at 6000rpm for 5min, leave only 100μl of supernatant to resuspend the bacterial precipitate and spread it onto the target plasmid-resistant LB plate.

4. Invert the plate and incubate at 37℃ for 14h, or at 30℃ for 20h.

5. Pick a single colony into LB liquid medium, add the corresponding antibiotics, incubate at 220rpm for 14h, and extract the plasmid according to the experimental needs and the instructions of the plasmid extraction kit.
