Transfection (i.e., delivery) of genes, RNA, or proteins into cells is a foundational technique in the life sciences. Successful transfection is critical for a range of applications, including studies of gene expression, gene knockdown (i.e., RNAi), genome editing, and protein expression for biopharmaceuticals. Furthermore, advances in mammalian cell transfection technologies, such as in vivo delivery, have proven invaluable to clinical research, with these techniques playing pivotal roles in the development of vaccines as well as cell and gene therapies.

Packaging must protect the product inside—but that doesn’t have to mean sacrificing sustainability. Lipofectamine products are shipped at ambient temperature, diverting 24,000 ft3 of Expanded Polystyrene (EPS) coolers from landfills annually. We reduce the carbon footprint from packaging and shipping these products by 80 tons (CO2 equivalents).
We've made it easier for you to quickly find and buy products for every step in your transfection workflow.
