By Sample Type


By Cell Type

Our new Lipofectamine® Reagent Specific Protocols have been newly optimized for efficiency, viability, and reproducibility across a broad range of cell types. This is often the best place to start, especially in a new cell line. If you find this doesn’t work for your specific cell type, then you can you look to our cell specific protocols for further optimization.
