ATTO 680 DPPE Labeled Phospholipid 1 mg
Product No. AD-680-151 ATTO-Dye Labeled Phospholipids In recent years the investigation of biological membranes, e.g. intracellular membranes of live cells, plasma membranes etc., has become a major subject of interest. As a result there is a growing demand for fluorescent dye-labeled lipids, in particular glycero-phospholipids, to be incorporated in biological membranes. ATTO offers a variety of glycero-phospholipids, carrying one or two fatty acid chains (lipophilic groups) and a phosphate ester residue (hydrophilic group). ATTO-dye fluorescent phospholipids are labeled at the hydrophilic head group. After incorporation in, e.g., a plasma membrane (phospholipid bilayer) the fluorophore is located at the water/lipid interface of the membrane.

Characteristic features of the label are strong absorption, high fluorescence quantum yield, good water solubility, and high thermal and photo-stability. ATTO 680 is a zwitterionic dye. After coupling to a substrate the dye moiety is electrically neutral. ATTO 680 is a strong electron acceptor. Its fluorescence is efficiently quenched by electron donors like guanine, tryptophan, etc.
The fluorescence is excited most efficiently in the range 645 - 695 nm. A suitable excitation source for the dye is the Krypton-Ion laser using the 676 nm line or a diode-laser emitting at 670 nm.
