N-TER Nanoparticle siRNA Transfection System

siRNA Delivery to Hard-to-Transfect Cell Types

Traditional lipid-based siRNA transfection reagents exhibit a number of drawbacks, including a limited ability to transfect into a variety of cell types, such as primary, neuronal, differentiated, and non-dividing cells.

Our N-TER Nanoparticle siRNA Transfection System is based on a peptide transfection reagent specifically designed to bypass these limitations and allow for efficient delivery of siRNAs into these historically recalcitrant eukaryotic cell types.

Benefits of the N-TER Nanoparticle siRNA Transfection System:

  • Superior transfection of historically difficult-to-transfect cells, including primary, neuronal, differentiated and non-dividing cells
  • Quick delivery of siRNA into cells, with reduced cytotoxicity as compared to lipid-based reagents
  • Stable N-TER/siRNA nanoparticles can be stored at -20 °C for up to 1 year
  • Simple protocol easily adapted for high-throughput and reverse transfection applications
