Announcement - Clontech Laboratories, Inc. Releases the Xfect™ Protein Transfection Reagent

Dec 01, 2010, 09:00 ET from Clontech Laboratories, Inc.

MOUNTAIN VIEW, Calif., Dec. 1, 2010 /PRNewswire/ -- Clontech Laboratories, Inc., a wholly-owned subsidiary of Takara Bio Inc., today announced the upcoming (December 6th) release of its novel Xfect™ Protein Transfection Reagent. This new protein transfection reagent uses a cell-penetrating peptide developed at Clontech to bind and transport active proteins directly into a wide variety of mammalian cell types with little to no toxicity. Significantly, even hard-to-transfect human suspension cell lines and mouse embryonic stem cells can be efficiently transduced using this novel reagent.

Carol Lou, General Manager of Clontech Laboratories, Inc., comments: "We are pleased to announce the expansion of our Xfect Transfection Reagent product line to include this innovative Protein Transfection Reagent, as part of our commitment to enhancing and simplifying gene and protein delivery."

There is a growing demand for tools to deliver active proteins directly into cells for studies including transcriptional regulation, cell cycle, apoptosis, oncogenesis, epigenetics, and cell regeneration, e.g.  iPS and trans-differentiation. Compared to traditional gene expression studies using transfected DNA, protein transfection is extremely rapid (1–2 hours compared to 12–24 hours) because it bypasses cellular processes such as transcription and translation. Protein transfection also facilitates studies involving transient effects of proteins, and avoids potentially harmful, random DNA integration into the genome of the target cells.
