Avalanche® transfection reagents have the broad spectrum for the transfection of large plasmid, mRNA, siRNA, and/or other type of nucleic acids. This feature makes Avalanche® transfection reagents the best option for co-transfection of different type and/or size of nucleic acids.  The following are the reasons for the broad spectrum:

The key components of Avalanche® transfection reagents are mixtures of cationic lipids and cationic polymers, which contain all three types of amines: primary, secondary, and tertiary amines. The three types of amines have different positive charge strength, hence have different capabilities to combine with negative charged anions.

As anions, different types and sizes of nucleic acids have different densities and quantities of negative charges.

With optimized ratios of different cationic lipids and polymers, hence optimized ratios of the three different type of amines, together with optimized protocols, our Avalanche® mixtures have the optimized strength of positive charges that ensure them to efficiently combine with different type of nucleic acids of a variety of negative charge densities and quantities, and compact them into the right sizes of nanoparticles with the right densities of positive charge (zeta potential) on their surface. The optimized size and the right strength of zeta potential of the nanoparticles are the keys for the nanoparticles to interact efficiently with negatively charged cell surface, and trigger endocytosis process.
