ATTO 488 DMPE Labeled Phospholipid 5 mg
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-TEC 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.

ATTO 488
ATTO 488 is a hydrophilic fluorescent label with excellent water solubility. The dye exhibits strong absorption, high fluorescence quantum yield, and exceptional thermal and photo-stability. Thus ATTO 488 is highly suitable for single-molecule detection applications and high-resolution microscopy such as PALM, dSTORM, STED etc. Additionally the dye highly qualifies to be applied in flow cytometry (FACS), fluorescence in-situ hybridization (FISH and many more. The fluorescence is excited most efficiently in the range 480 - 515 nm.
A suitable source of excitation is the 488 nm line of an Argon-Ion laser.
