Fuse-It-mRNA easy

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

Fuse-It-mRNA easy

  • NEW: no sonication step required
  • Immediate mRNA translation—protein synthesis detectable after 15–30 minutes
  • 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
  • mRNA transfer completed within 5–20 minutes
  • No endocytosis involved
  • No lysosomal degradation needed
  • No gene 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
