Transfection reagents allow scientists to manipulate the genetic material of cells by introducing exogenous nucleic acids sequences. While transfection is commonly used to alter gene expression in cell biology experiments, advanced gene editing methods such as CRISPR/Cas 9 rely on transfection to successfully introduce nucleases and guide RNA into the host cell. Lipid-based transfection reagents are most effective in actively proliferating cells and are valuable for a variety of applications, including protein expression and the overexpression of mutant genes. ATCC’s transfection reagents are cationic lipid-based; because of their positive charge, these reagents interact with the negatively charged backbone of nucleic acids and cell membranes. Cationic lipid transfection is a fast, simple, and reproducible process for introducing DNA, RNA, or other oligonucleotides into eukaryotic cells. This classic method offers highly efficient transfection for a broad range of cell types, including adherent and suspension cell lines, as well as many primary cells and stem cells. Our exceptional transfection reagents, combined with ATCC's technical know-how, will enable your transcriptional and translational gene studies.

Cationic lipids have become the tool of choice for many researchers. ATCC’s line of transfection reagents, GeneXPlus and TransfeX are tailored for effective nucleic acid transfer into a wide variety of cells for a multitude of applications, including:
