Nucleic Acid Transfection Kits for Primary Neurons


• 95% cell transfection efficiency
• No observed cytotoxicity
• Gene knockdown via siRNA expression
in vitro and in vivo applications
• Non-viral transfection




• siRNA transfection for gene knockdown via RNAi both in vitro and in vivo


Top Right: Enriched (>90%) E18 primary rat cortical neurons treated at DIV12 with Neuro9 siRNA against HPRT. HPRT mRNA assayed by qPCR 48h post-treatment. *** P < 0.001


Middle Right: Enriched (>90%) E18 primary rat cortical neurons treated at DIV7 with Neuro9 siRNA against HPRT for 48 hours. Cell viability assayed using PrestoBlue.


Bottom Right: Primary rat neurons were treated at various stages of maturity with Neuro9 siRNA against PTEN. Neuro9 is well tolerated and can be applied at DIV ≥ 2. This flexibility opens doors to new experimental possibilities. *** P < 0.001

Neuro9 In Vitro Cell Culture & Transfection

Images: Fluorescently labeled Neuro9 (red) is used to observe uptake by MAP2+ neurons (green).

Plot: Flow cytometry indicates Neuro9 uptake in >95% of cells

Neuro9 In Vivo Transfection
Neuro9 (red) was locally injected into rat somatosensory cortex. Brains were removed 5 days later, sliced and imaged. Calcein-AM dye (green) indicates neurons were alive when imaged. Western blots from samples 1mm from the injection site exhibit significant knockdown of target gene PTEN compared to “control” samples taken from the opposite hemisphere and samples treated with Luc siRNA.
