XfectTM Protein Transfection Reagent

Description

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. Our products are to be used forResearch Use Only.

Back Back Simple, rapid protein transfection with Xfect Protein Transfection Reagent.Xfects reagent cell-penetrating activity enables proteins to be transported across membranes of mammalian cells. Back 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 :15451556. . Back 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 mug 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 .
