LI-COR Introduces CellVue® Dye Kits for Fluorescent Labeling of Cell Membranes

Mar. 3, 2009, Lincoln, NE: LI-COR Biosciences in partnership with Molecular Targeting Technologies, Inc (MTTI) introduces two new fluorescent imaging kits for cell membrane labeling. The kits use proprietary labeling technology comprising a CellVue® Dye and a cell labeling diluent to rapidly and stably integrate dye into the phospholipid membrane of cells or other membrane-containing bioparticles by non-covalent interactions. Cells can be analyzed immediately and labeled cells can be tracked for an extended period of time because the dyes are incorporated rapidly and maintained stably through strong hydrophobic interactions. The CellVue® dyes provide the researcher with valuable tools for a multitude of both in vivo and in vitro cell studies when fluorescent membrane labels for tracking and identification of cells are required.

The CellVue® dyes are provided in an easy to use kit format comprised of a solution of the dye in ethanol and a cell labeling diluent designed to maintain cell viability while maximizing solubility and staining efficiency. The simple membrane labeling protocol provided with the kit is applicable to almost any type of cell or organism. The excitation and emission properties of CellVue® Burgundy and CellVue NIR815 dyes are compatible with LI-COR's Odyssey® Infrared Imaging System and the Pearl® Imager, a new small animal imaging platform as well as a range of commercially available near-infrared fluorescent plate readers, flow cytometers, in vivo and in vitro fluorescent imaging systems, and confocal microscopes.
