Takara Xfect Protein Transfection Reagent \100 Rxns

The Xfect Protein Transfection Reagent allows the delivery of proteins and antibodies into cell lines in less than two hours. Delivery efficiency is high (60-99%), and proteins retain their biological activity. This kit contains Xfect Protein Transfection Reagent, Xfect Protein Buffer, deionized water, and a Beta-Galactosidase Control.

Simple, rapid protein transfection with Xfect Protein Transfection Reagent.Xfect’s reagent cell-penetrating activity enables proteins to be transported across membranes of mammalian cells.

How fast is direct protein transfection?.We transfected human recombinant caspase-3 using Xfect Protein Transfection Reagent and detected completion of apoptosis after just 2 hr, demonstrating that protein transfection using Xfect reagent is both fast and delivers active protein (Panel B). Other methods for inducing apoptosis require 12 hr for completion of Annexin V staining (Martin, S. J. et Al. (1995) J. Exp. Med. 182(5):1545–1556.).

Xfect Protein Transfection Reagent delivers up to 8X more active beta-galactosidase into HeLa cells than the leading competitor, Product C. Panel A.Xfect Protein Transfection Reagent or Product C was used to transfect Jurkat cells with various amount of beta-galactosidase (beta-gal) according to the manufacturers’ recommended protocol. One hour post-transfection, the cells were assayed for beta-gal activity using ourLuminescent beta-galactosidase Detection Kit II (Cat. No. 631712). Xfect Protein Transfection Reagent displayed a far higher signal for beta-gal than didProduct C.Panel B. HeLa cells transfected with 4 µg of beta-gal demonstrated higher efficiency and a higher amount of beta-gal protein per cell when transfection was performed with Xfect Protein Transfection Reagent (middle panel) than with Product C (right-hand panel).
