Frequently asked questions (FAQs)

I'm seeing cell death after transfection using Lipofectamine RNAiMAX Reagent. What should I do?

Remove antibiotics from the medium during transfection, as this can cause stress leading to cell death. Try adjusting both lipid and siRNA quantities. Use cells with lower passage number for better viability. Consider assaying for microbes such as Mycoplasma that are not detected easily in cell culture.

I accidentally froze my Lipofectamine RNAiMAX Reagent. Can I still use it?

Freezing can alter the integrity and composition of the lipid particles. The performance of the reagent may be affected and it may only work for the first week or so. It is safer to use a new vial.
