Sigma-Aldrich’s N-TER™ nanoparticle siRNA transfection peptide-based system was developed to circumvent a number of drawbacks associated with lipid-based siRNA transfection agents.

Transfection facilitates the controlled introduction of DNA or RNA, creating new avenues in the exploration of gene functions and cellular pathways without the need to use viral vectors.
