Transfection Reagents

Reagents for Your R&D Activity

We developed broadly acting transfection reagents to modify mammalian cells with plasmid DNA, siRNA, mRNA and other nucleic acids. The foundation of our transfection reagents is based on cationic lipopolymers with optimal balance of cationic charge and hydrophobic (lipid) group. By systematically altering the polymeric backbone and the nature of lipid group, a library of transfection reagents has been generated. Some of the transfection reagents are broadly acting, functioning in different cell types with different nucleic acids. Others display high specificity, where they are exceptionally effective in particular cell types for particular nucleic acid delivery.

The key advantages of our delivery vehicles are:
