1,2-Dioleoyl-sn-glycero-3-phosphoethanolamine, pyrene-labeled

18:1 Pyrene PE may be used:

• as a quencher of protein intrinsic emission in intrinsic tryptophan quenching assays of membrane proximity
• to incorporate in vesicle membranes
• to label vesicles to confirm the presence of hybrid vesicles in flow-cytometric analysis

Phosphatidylethanolamine (PE) can serve as a lipid chaperone th at supports in the folding of membrane proteins. It plays a key role in the activity of respiratory complexes. PE also participates in the initiation of autophagy.
