TurboFect™ Transfection Reagent (Thermo Scientific™)

Thermo Scientific TurboFect Transfection Reagent is a highly efficient, easy-to-use, non-immunogenic transfection reagent for delivery of DNA plasmids and expression vectors into eukaryotic cells.

Features of TurboFect Transfection Reagent:

• High transfection efficiency of a wide variety of cell types
• No optimization required for most cell lines
• Excellent transfection efficiency in the presence or absence of serum
• Minimal cytotoxicity
• Ready-to-use—no need to reconstitute, dilute or manipulate

Applications of TurboFect Transfection Reagent :
• Stable and transient transfection or co-transfection of DNA or RNA

TurboFect Transfection Reagent is a sterile solution of a proprietary cationic polymer. TurboFect Reagent interacts with DNA to form small, stable, highly diffusible complexes which are readily endocytosed. The reagent creates a proton-sponge effect that buffers endosomal pH by provoking massive proton accumulation and passive chloride influx. As a result, rapid osmotic swelling of the endocytosed DNA-complex causes it to rupture in the cytosol, allowing translocation of DNA to the nucleus. TurboFect Reagent is ideal for transfection of a variety of cells, including primary and difficult-to-transfect cells.

siPORT™ NeoFX™ Transfection Agent (Invitrogen™)

This Ambion® lipid-based formulation can be used to efficiently transfect adherent cells with siRNA as they are subcultured—without increased cytotoxicity. It is provided in one tube containing 0.4 mL.

• Versatile—works with a broad range of cell lines
• Reproducible—produces consistent results, lot-to-lot, plate-to-plate, and well-to-well
• Efficient—performs with high siRNA transfection efficiency, allowing use of low siRNA concentrations to minimize nonspecific effects
• Fast—reverse-transfects cells as they are plated, saving a day

Gene silencing experiments often call for critical, but time-consuming optimization experiments. siPORT™ NeoFX™ Transfection Agent refines siRNA transfection protocols resulting in less optimization. From start to finish, successful gene silencing experiments can be completed in as early as 24 hours. This streamlined protocol can be adapted to a wide range of cells and experimental designs, including high-throughput applications.

Reverse-Transfect Cells as They are Plated, Saving a Day
Just add siPORT™ NeoFX™ to your diluted siRNA, incubate to form transfection complexes, add the complexes to the culture wells, and overlay with cells. This new streamlined protocol, named "neofection", will save researchers a full day of valuable time when compared to traditional plated transfection procedures. The transfection complexes are active and stable even in the presence of serum, so there is no need to remove or replace media following transfection.

Optimized for Lower siRNA Concentrations and High Reproducibility
Recent reports indicate that siRNA concentrations of 100 nM or higher can lead to nonspecific changes in gene expression (off-target effects) in mammalian cultured cells. Reducing the amount of siRNA used for transfections to 1–20 nM minimizes these nonspecific effects, while still providing extensive silencing of the target gene. siPORT™ NeoFX™ Transfection Agent efficiently transfects low concentrations of siRNA. Furthermore, this agent delivers high performance among multiple wells for replicate samples and between different lots of the transfection agent.

Compatible with a Broad Range of Cell Lines
The agent has been used successfully to deliver siRNA into many cell types, including MCF-7 (human breast adenocarcinoma), HT-29 (human colorectal adenocarcinoma), HeLa-S3 (human cervix adenocarcinoma), HeLa (human cervix adenocarcinoma), HepG2 (human hepatocellular carcinoma), BJ (human foreskin fibroblast), A549 (human lung carcinoma), UMR106 (rat osteosarcoma), SKOv3 (human ovarian carcinoma), and SKNAS (human bone marrow neuroblastoma).
