Nucleic acid delivery is a focus area for therapeutic research across the globe. Nucleic acid cargo such as DNA, mRNA, siRNA, and CRISPR/Cas-9 gene editing technologies are negatively charged (anionic) and thus, to sequester and deliver the cargo, the delivery system needs a positively charged (cationic) component. Unlike ionizable lipids, fixed cationic lipids are constantly charged in biological environments regardless of the pH.

Fixed cationic lipids have been proven to be good transfection agents in liposomes and lipid nanoparticles. Generally considered non-toxic at lower concentrations, these lipids do present some toxicity concerns when used in higher concentrations due to the tetra substituted ammonium moiety. Avanti offers a wide range of proven fixed cationic lipids such as DOTMA or DOTAP, but new, innovative cationic lipids are constantly being added. Check out our fixed cationic lipid offerings and fuel your lipid-based nucleic acid delivery research today!
