Fuse-It-mRNA for mRNA Transfection

A fusion reagent for rapid mRNA transfection into the cytoplasm of living cells

Technical Features

  • Immediate mRNA translation leads to protein synthesis detectable after only 15-30 minutes
  • Beniag’s fusion mechanism works perfectly in proliferating cells as well as in non-proliferating cells (e.g. cardiomyocytes)
  • Highly efficient and biocompatible, especially in primary cells (e.g., neurons or HUVECs) and stem cells


  • mRNA translation and degradation studies
  • Protein biochemistry studies: synthesis, folding, processing, stability, localization, degradation
  • mRNA transfer into primary cells without generating genetically modified organisms (GMO)
  • Genome engineering by RNA-only CRISPR/Cas technology

Technical Features

  • Lipofection-independent transfer of mRNA into living cells
  • the transfer of mRNA is completed within 5–20 minutes
  • No endocytosis involved
  • No lysosomal degradation needed
  • without transfer to the nucleus
  • Protocol optimized for the transfer of functionally capped and polyadenylated mRNA
  • No Biosafety Laboratory Level 1 or 2 necessary
  • Excellent biocompatibility with low cytotoxicity

Membrane Fusion – The Direct Way to Protein Expression

The novel mRNA transfection reagent Fuse-It-mRNA uses fusogenic liposomes for mRNA transfer without endosomal release
