Basic Vector Information

The NL4 - 3 mCherry Luciferase vector is an important tool for studying HIV - 1 latency.

It combines mCherry and Luciferase genes connected by a T2A ribosomal skip sequence. Under the same LTR - driven mRNA, they are expressed as separate proteins with Nef under an IRES element.

This dual reporter gene system allows simultaneous monitoring of activated cell number (mCherry) and reactivation strength (Luciferase). It accurately reflects HIV - 1 states, providing a comprehensive perspective for latency mechanism study. Its advantages include comprehensive information acquisition, rapid latency establishment and reactivation detection in primary CD4 T cells and different subsets, and broad application prospects for evaluating activator effects and studying subset differences, supporting HIV latency research and treatment strategy development.

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.
