Cell Penetrating Peptides

The internalization of bioactive cargo into live cells has become an area of fast growth. In particular, the use of Cell Penetrating Peptides (CPPs) as helper-molecules for overcoming cell membrane barriers enabled researchers to transfect numerous cell lines and cell types with a large number of proteins & enzymes, nucleotides, and nucleic acids.

In our CPP section we offer novel kits and formulations that
  • are applicable to many cell lines including both adherent and suspension cells
  • have low toxicity for live cells
  • are targeted to different internalization mechanisms thereby achieving higher success rates
  • enable efficient transduction of nearly 100%
  • minimize artefacts due to complete post-internalizational break down of CPPs
  • allow straight forward experiments, no expensive equipment necessary
  • contain selected helper reagents for fine-tuning of experimental set ups
  • are safe to use without any special precautions

For detailed information please refer to the   General Manual.
