TransfeX™ Transfection Reagent (ATCC® ACS-4005)

Permits and Restrictions

View Permits View Restrictions

Product Format 500 µL
Storage Conditions Store at 2°C to 8°C
Shipping Information Refrigerated Bricks
Applications Transient transfection, stable transfection, gene expression, protein production, and genetic manipulation.

Cationic lipid compound contained in an aqueous based solution. Reagent is designed for transfection of primary cells and hard-to-transfect cell lines.  TransfeX Transfection Reagent provides high efficiency with low cell mortality. Cell line-specific protocols can be found here.

Biosafety Level N/A
Quality Control Specifications The molecular weight was determined by Mass Spectroscopy to be consistent with the expected structure.
Sterility Testing No evidence  of bacterial or fungal contamination. Mycoplasma testing was negative for the presence of mycoplasma.
Functional Testing HeLa cells are transfected with a lacZ reporter plasmid. The peak activity and the cytotoxicity for the test lot is determined in a beta-galactosidase functional assay and compared to control lot.
