COSFect is a highly efficient, lipid-based transfection reagent specifically developed for COS cell lines

COSFect is based on Tee-Technology (“Triggered Endosomal Escape”), a technology that combines and exploits the properties of cationic lipids and polymers to achieve extremely efficient nucleic acids delivery into cells. The cationic design of COSFect reagent allows high nucleic acid compaction for transport into COS cells. This reagent is composed by biodegradable lipids resulting in high viability.



  • Highly efficient with COS cell lines
  • Ready-to-use; no need for additional buffer
  • Low nucleic acid amount; minimized toxicity
  • High level of nucleic acid compaction
  • Easy and straightforward protocol
  • Compatible with any culture medium; medium change not required



  • Nucleic acids transfection into COS lineages



  • CF10500 – COSFect Transfection Reagent, 500μl
  • CF11000 - COSFect Transfection Reagent, 1ml
  • CF12500 - COSFect Transfection Reagent, 5ml
