Co-transfection with DNA Strategy for PNA Delivery
Co-transfection of DNA is a technique increasingly used by biological researchers. Commonly used applications of co-transfection are virus production, protein-protein interaction research, etc. Among them, the PNA-DNA hybrid cationic liposome transfection method can effectively increase the uptake of PNA by cells.
Transfection Technology
Transfection is the process of artificially introducing nucleic acid into cells by means other than viral infection. Various chemical, biological, or physical methods are used to introduce exogenous nucleic acids, resulting in changes in cell characteristics. All transfection strategies can be roughly divided into two types:
- Transient transfection. The introduced nucleic acid exists in the cell for a limited time.
- Stable transfection. Allows long-term maintenance of the foreign nucleic acid in the transfected cells and their progeny.
Co-transfection refers to the simultaneous transfection of two independent nucleic acid molecules, such as DNA and PNA. Co-transfection is a common procedure for stable transfection.
PNA and Complementary DNA Co-transfection Protocol
- The PNA is reversely complementary to the target sequence nucleotide and is fluorescently labeled, and the 3'end of the DNA is complementary to the 5'end of the PNA. The sequence and complementation are made according to the actual situation.
- The cells can be provided by the customer or directly by the Creative Peptides .
- The equal amount of PNA and DNA solution is annealed in the PCR machine to form a combination of PNA and DNA. When the cells are cultured to a cell confluency of 30% to 50%, a cationic liposome-mediated transfection test is performed, and the cells are collected at different times for related testing.
- Use flow cytometry to detect PNA transfection effect.
- Detect the effect of PNA on cell gene expression by RT-PCR.
