Labeled Phospholipids

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.

Currently we provide the phospholipids

1,2-dipalmitoyl-sn-glycero-3-phosphoethanolamine (DPPE),
1,2-dioleoyl-sn-glycero-3-phosphoethanolamine (DOPE),
1-palmitoyl-2-hydroxy-sn-glycero-3-phosphoethanolamine (PPE)
1,2-dimyristoyl-sn-glycero-3-phosphoethanolamine (DMPE), and
1,2-dilauroyl-sn-glycero-3-phosphoethanolamine (DLPE)

labeled with ATTO-dyes.

Other labeled phospholipids including sphingolipids such as sphingomyelin are available on request. Please send an e-mail to info@atto-tec.com.
