Optimized product to biotinylate surfaces of living cellsOptimized product to biotinylate the surfaces of living cells

Technical Features

  • Fusogenic liposomes are used as carriers to transfer biotinylated lipids from liposomes into the plasma membrane of cells by fusion.
  • Superb fusion efficiency of 80 to 100% independent of the cell type used.
  • Fusion process completed within 1 to 20 minutes with superior biocompatibility.


  • Cell surface functionalization and targeting using biotin-avidin coupling
  • Cell separation using avidin coated magnetic beads
  • Attachment of living cells to distinct pre-coated surfaces
  • Tremendous biotechnological and therapeutic approaches

After fusion cells can be used immediately for further analysis. Biotin can be visualized by anti-biotin antibodies or bound to avidin, neutravidin and streptavidin, respectively. Depending on experimental needs, fusion can be detected by fluorescence.
