Helix-IN™ DNA Transfection Reagent


Polyfection-based, powerful broad-spectrum transfection from classic cell lines to difficult-to-transfect cells

Helix-IN™ DNA Transfection Reagent opens up new possibilities for addressing issues of classical transfection technologies. Helix-IN™ is based on Polyfection with a novel patented Cationic Hydroxylated Amphiphilic Multi-block Polymer (CHAMP Technology). 

The particularity of the CHAMP technology comes from the fact that the bi-functional cationic biopolymer binds and condenses DNA to an unprecedented level what contributes to cytosol delivery, that a pH responsive and cleavable linker improves cellular delivery by favoring endosomal membrane destabilization and that it serves as a DNA shield and nuclear uptake facilitator. Thus, this novel bi-functional co-polymer is biocompatible, ionizable, pH responsive and biodegradable.

  • Enhanced transfection efficiency
  • Low cellular stress thanks to minimized toxicity
  • Higher viability thanks to preserved membrane stability
  • High Intracellular Protein Production
  • High secreted Protein Production 
  • Biodegradable – avoid secondary effects
  • Compatible with any culture medium
