Description

Highlights:

  • Suitable for transfection of DNA, mRNA, siRNA und miRNA
  • Suitable for cotransfection of DNA and RNA
  • Especially suitable for human cells
  • In many cases significantly increased transfection efficiency compared to common reagents
  • Decreases the cells´ability to detect nucleic acids

Eukaryotic cells have an innate immune system which makes them able to detect foreign substances such as lipopolysaccharides, bacterial or viral nucleic acids and proteins, and take action to inhibit invasion by potential pathogens. Moreover, the cells announce the presence of harmful substances to neighbouring cells via messenger molecules. As a consequence, these neighbours adopt defence modes without even having contact with the pathogens.

The finding that lipofection is also attacked by the defence measures of the innate immune system led us to develop the K2® Transfection System, consisting of the K2® Transfection Reagent and the K2® Multiplier. The K2® Transfection Reagent is based on powerful cationic lipids, while the Multiplier decreases the cells' ability to detect nucleic acids.

We were thus able to significantly increase transfection efficiency in many cases in comparison to traditional lipofection reagents, namely in transfection of DNA and mRNA. The K2® Transfection System is therefore suitable for transient and stable transfection of mammalian cell lines and primary cells with DNA (plasmids, bacmide), RNA (mRNA, miRNA, and siRNA), and modified nucleic acids (e.g. antisense oligonucleotides). Areas of application are particularly the production of proteins, antibodies, and viruses (e.g. adenoviruses, AAV, lentiviruses), cotransfections

of different nucleic acids, genome editing (e.g. CRISPR/Cas9, CRISPR/Cpf1) and gene silencing (gene knockdown).
