Lyophilized Lipid-based Transfection Reagent
LyoVec™ is a proprietary cationic lipid-based transfection reagent belonging to the family of phosphonolipids. This family was originally described by Floch et al., as efficient transfection reagents for both in vitro and in vivo use [1-2].
The major constituent of LyoVec™ is the phosphonolipid DTCPTA, which is coupled to DiPPE, a neutral lipid that helps destabilize membrane bilayers and increases the in vitro transfection efficiency of LyoVec™.
Applications of LyoVec™:
- Cationic lipid-based transfection reagent
- Nucleic acid complexing agent
The positive charge of the phosphonolipid enables LyoVec™ to bind to plasmid DNA, and the structure promotes fusion with cellular membranes for efficient DNA delivery.
Additionally, LyoVec™ can be used as a nucleic acid complexing agent to facilitate the cellular entry of RNA or DNA-based oligonucleotides, such as RIG-I ligands (e.g. poly(dA:dT)  and poly(I:C) ) and endosomal TLR7/8 ligands (e.g. ssPolyU ). This complexation step is crucial for inducing an effective response to the nucleic acids by pathogen recognition receptors.
