TransIT®-LT1 Transfection Reagent is a broad spectrum reagent that provides high efficiency plasmid DNA delivery in many mammalian cell types including primary cells. TransIT-LT1 is a low toxicity, serum-compatible transfection reagent that eliminates the need for any culture medium change. TransIT-LT1 is suitable for both transient and stable transfection and can be used for many applications such as gene expression, viral production, shRNA expression and promoter analysis.

TransIT-X2® Dynamic Delivery System is an advanced, non-liposomal polymeric system that enables high efficiency transfection of many cell types, including primary cells. TransIT-X2 can be used for DNA delivery, siRNA delivery or simultaneous delivery of DNA and siRNA. Transfections with TransIT-X2 do not require medium changes and can be carried out in serum-containing medium.
