PULSin® Protein Delivery

The delivery of protein and antibody using PULSin® represents a powerful approach for functional studies. With PULSin® you can target intracellular proteins with antibodies in living cells without a fixation step, as well as study the function of a protein by controlling the expression level and the expression time course.

PULSin® is composed of a proprietary cationic amphiphile molecule that forms non-covalent complexes with proteins and antibodies. Once formed, complexes are internalized via anionic cell-adhesion receptors and are released into the cytoplasm where they disassemble. The process is non-toxic and delivers functional proteins.Key Benefits:

  • Unique: One reagent for protein, antibody, and peptide delivery into mammalian cells.
  • Optimized: Efficient delivery in live primary cells and difficult to transfect cells.
  • Innovative: Easy to use alternative to chemical conjugation and viral transduction
