Tool Details

  • Tool name: NF70 peptide
  • Alternate names: NickFect7
  • Tool type: Proteins
  • Tool sub-type: Synthetic Peptide
  • Expression system: Synthetic
  • Function: siRNA delivery
  • Description: This peptide can be used to transport siRNA into cells. Use of cell-penetration peptides can increase the transport efficiency of extracellular synthetic nucleic acids, such as siRNAs, to help increase concentration of the siRNA at the desired cellular location. This peptide is based on NickFect55 (NF55) which is a peptide that can efficiently transport plasmid DNA into cells in vivo. To improve the efficiency of nucleic acid delivery, this peptide has been developed to improve the intracellular release mechanism resulting in higher local dosage of the cargo. The pH sensitivity of the peptide allows for association to siRNA cargo, transport into cells, and dissociation of the siRNA in the appropriate cellular compartment (lysosomal or endosomal compartments).
