Abstract: The present development is a transfection reagent prepared by ionic interaction of colostrum powder-derived exosomes and a polycation. The resulting exosome-polycation matrix, or EPM, is entrapped with biologic materials, such as siRNA, mRNA, antisense oligo or plasmid DNA or a plasmid DNA expression construct.
