Hieff Trans: Comprehensive Cell Transfection Solutions, Adaptable to Various Cell and Nucleic Acid Types

Cell transfection is a technique for introducing exogenous nucleic acids (such as DNA, mRNA, siRNA, miRNA, etc.) into cells, and it plays a crucial role in modern biomedical research. As scientific research continues to delve deeper, the demand for a variety of cell types has also become increasingly diverse, ranging from common HEK293 cells to special types of tumor cells and primary cells, each with its unique characteristics and requirements. Similarly, different types of nucleic acids also require specific transfection strategies to ensure efficient and safe gene delivery. Therefore, choosing the right transfection reagent is essential for the success of the experiment.

Chemical transfection reagents are indispensable tools in cell biology research, which introduce nucleic acids such as DNA, mRNA, siRNA, miRNA, etc., into cells through different mechanisms to achieve gene expression, silencing, or functional studies. Currently, commonly used chemical transfection reagents mainly include liposome transfection reagents, PEI transfection reagents, and calcium phosphate transfection reagents, each with its unique advantages and applicable scenarios.

Principle

Advantages

Disadvantages

Liposome transfection reagent

1. Liposome transfection reagents have positive-charged lipids that bind to negatively-charged nucleic acids to form lipid-nucleic acid complexes.

2. These complexes are attracted to the negatively-charged cell membrane.

3. The cell engulfs the complexes into endosomes through endocytosis.

4. The "proton sponge" effect of the lipids in the complexes prevents endosome acidification, leading to membrane destabilization and rupture, releasing the complexes into the cytoplasm.

5. Small nucleic acids like siRNA, miRNA, or mRNA can work in the cytoplasm, while DNA needs to enter the nucleus to be expressed.

6. Once in the nucleus, DNA is transcribed into mRNA and translated into proteins, expressing the foreign gene.

1. Liposome transfection reagents offer high efficiency with various cell lines, including hard-to-transfect primary cells.

2. They are versatile, compatible with both adherent and suspension cells, and various nucleic acids like DNA, siRNA, and miRNA.

3. These reagents work well in serum-containing media, avoiding the need to remove serum and thus minimizing cell damage.

1. Liposome transfection reagents can be toxic to cells, especially at high concentrations or over long periods, potentially affecting cell survival and function.

2. They are more expensive compared to traditional methods like calcium phosphate transfection.

3. Their in vivo application is limited due to serum clearance, accumulation in lung tissue, and potential to cause strong inflammatory responses and high toxicity.

PEI transfection reagent

1. PEI, a positively charged polymer, binds to negatively charged DNA to form PEI-DNA complexes through electrostatic interactions.

2. These complexes attach to the negatively charged cell membrane.

3. Cells engulf the PEI-DNA complexes through endocytosis, forming endosomes.

4. The "proton sponge" effect of PEI causes endosomes to swell and burst in the acidic environment, releasing the complexes into the cytoplasm.

5. In the cytoplasm, PEI-DNA bonds break, allowing DNA to enter the nucleus, where it is transcribed and translated into proteins.

1. PEI transfection reagents form stable complexes with DNA, enhancing transfection efficiency.

2. They have lower cytotoxicity compared to other cationic polymers, preserving cell viability and function.

3. PEI reagents offer a cost-effective solution, especially for large-scale transfections like viral vector production.

4. PEI reagents are available in GMP-grade for clinical and commercial production, ensuring quality and compliance.

1. PEI transfection reagents have limited versatility, primarily used for DNA and less effective with other nucleic acids like mRNA, siRNA, and miRNA.

2. They show high efficiency in specific cell types, such as HEK293 cells, for virus packaging and protein expression, but perform poorly with difficult-to-transfect cells.

Calcium Phosphate transfection reagent

1. DNA/calcium phosphate co-precipitates form in HEPES buffer with phosphate, where DNA's negative charge binds to positive calcium ions.

2. Cells engulf these co-precipitates, which stick to their surface, through endocytosis, a critical step for transfection efficiency.

3. Inside cells, the co-precipitates release DNA, which can lead to transient expression or stable integration into the genome.

1. Calcium phosphate transfection is cost-effective, suitable for labs with limited budgets.

2. It's easy to perform, requiring simple steps and minimal technical skill.

3. It can be used for both transient protein expression and creating stable cell lines.

1. Calcium phosphate transfection efficiency is variable and sensitive to factors like pH and DNA purity, which can lead to failed transfections, especially with impure DNA.

2. It's not suitable for all cell types, mainly used for HEK293 cells, and less effective for primary cells and some other cell types.

Case Presentation

In a 6-well plate system, GFP-expressing plasmids were transfected into HEK293 cells using YEASEN 40802ES transfection reagent and a competitor's transfection reagent. The GFP expression in transfected cells was observed under a microscope 48 hours post-transfection. The performance of YEASEN's transfection reagent was superior.

In a 12-well plate, HEK293 cells were transfected with a total of 1 μg of plasmid DNA; using 3 μL of transfection reagent, it was possible to successfully co-transfect two plasmids.
