Optimized product to efficiently label the plasma membranes of live cells


Technical Features

  • Fusogenic liposomes are carriers for lipophilic dyes to label cellular plasma membranes by fusion
  • Superb fusion efficiency of 80 to 100% independent of the cell type used
  • Fusion process is completed within 1 to 10 minutes with superior biocompatibility
  • Various emission spectra available depending on experimental needs


  • Live cell labeling for any kind of microscopic technique.
  • Labeling of single cell types for co-culture experiments.
  • Labeling of cells for flow cytometry and FACs.
  • Biotechnological and therapeutic approaches.

After fusion, cells can be analyzed immediately. Cell labeling by fusion is a highly superior technique to any other labeling product available. It is extremely efficient, leading to sufficient labeling densities within seconds for most cell types. Labeling works on adhered cells as well as on cells in suspension, independent of the medium conditions used.
