Clontech Laboratories, Inc. Makes the DsRed-Monomer Fluorescent Protein Available to For-Profit Entities

Sep 18, 2006, 01:00 ET from Clontech Laboratories, Inc.

    MOUNTAIN VIEW, Calif., Sept. 18 /PRNewswire/ -- Clontech, a wholly
 owned subsidiary of Takara Bio Inc., announced today that it is now making
 the DsRed-Monomer fluorescent protein available to for-profit entities for
 both research and commercial use. Previously, the DsRed-Monomer was only
 available to not-for-profit organizations.
     The DsRed-Monomer fluorescent protein is a highly engineered monomeric
 form of the normally tetrameric Discosoma sp. red fluorescent protein. It
 is the latest addition to Clontech's extensive Living Colors(R) line of
 fluorescent proteins. The red-shifted emission spectra of the Living Colors
 red fluorescent proteins makes them ideal reporters for multi-color
 labeling applications or to avoid green auto-fluorescence. The new
 DsRed-Monomer retains these valuable red-shifted spectral properties and is
 also monomeric, making it especially useful as a fusion tag. The new
 variant's monomeric structure has been confirmed by several independent
 methods, including gel filtration and native polyacrylamide gel
 electrophoresis. Additionally, its functionality has been validated by
 fusion to a wide variety of proteins with diverse functions and subcellular
     "As the premier supplier of fluorescent protein technologies to
 researchers since 1994, Clontech is proud of its extensive collection of
 fluorescent protein tools, which now includes the DsRed-Monomer. The Living
 Colors line provides the broadest spectral array of monomeric and
 multimeric fluorescent proteins available -- from blues, like our AmCyan,
 through far red-shifted proteins, such as HcRed," said Carol Lou, General
 Manager of Clontech Laboratories, Inc.
     Clontech's Living Colors fluorescent proteins have broad applications
 in basic research and drug development. Proven uses include monitoring
 signal transduction pathways; observing gene expression in live or fixed
 cells; tracking subcellular organelles and proteins; and labeling to
 identify and isolate specific populations of cells. Clontech's Living
 Colors fluorescent proteins have been used successfully in both animals and
 plants. Significantly, due to the wide spectral separation of the Clontech
 Living Colors fluorescent proteins, it is possible to visualize multiple
 events simultaneously by both microscopy and flow-cytometry.
     Clontech Laboratories, Inc. develops, produces, and markets
 leading-edge biological products to the life science market worldwide.
 Clontech has over 2,000 products that enable life science researchers to
 study genes, their products, and their cellular function through the use of
 innovative and powerful tools for gene cloning, labeling, and expression;
 as well as for elucidating protein:protein interactions; isolating and
 purifying DNA and proteins; and conducting a wide variety of PCR
 experiments. Clontech is a wholly owned subsidiary of Takara Bio Inc. For
