ATTO 740 DMPE Labeled Phospholipid 5 mg
Product No. AD-740-195 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 dye are strong absorption and good fluorescence as well as excellent thermal and photo-stability. ATTO 740 is a cationic dye. After coupling to a substrate the dye carries a net electrical charge of +1. ATTO 740 is a pH sensitive product. While practically stable up to pH 7.4 (PBS-buffer), it slowly degrades at higher pH. If exposed to higher pH for coupling purposes, we recommend reducing the pH immediately after completion of the reaction. The fluorescence is excited most efficiently in the range 720 - 755 nm.
