Abstract: The use of short interfering RNA (siRNA) for knockdown of gene expression has become a powerful tool in molecular and cell biology. Some applications require the use of low siRNA concentrations (less than 5 nM), for example, to decrease the possibility of non-specific effects.

We have developed a transfection reagent, HiPerFect Transfection Reagent, which allows efficient gene knockdown with siRNA concentrations from 1 nM–10 nM, depending on the cell type and siRNA used. HiPerFect Transfection Reagent has been tested and validated for many cell types, including primary cells. Effective knockdown in primary cells demonstrates that HiPerFect Transfection Reagent ensures low cytotoxicity levels.

A Fast-Forward siRNA Transfection Protocol has been developed for rapid transfection with HiPerFect Transfection Reagent. This protocol allows cell seeding and transfection on the same day.

A reverse transfection protocol has been developed that is ideal for use in high-throughput applications. In reverse transfection, siRNA is spotted into wells, followed by addition of HiPerFect Reagent. After complex formation, cells are added to the wells.
