Uses

1-palmitoyl-2-(9-(3-pent-4-ynyl-3-H-diazirin-3-yl)-nonanoyl)-sn-glycero-3-phosphocholine (16:0-pacFA PC) might be used to label hydrogenated zwitterionic bicelles (HZB) and hydrogenated anionic bicelles (HAB).

General Description

The pacFA lipid attached to 1-palmitoyl-sn-glycero-3-phosphocholine, contains a photoactivable diazirine ring with a clickable alkyne group.

Biochem/physiol Actions

1-palmitoyl-2-(9-(3-pent-4-ynyl-3-H-diazirin-3-yl)-nonanoyl)-sn-glycero-3-phosphocholine (16:0-pacFA PC) may be used for a global analysis of protein–lipid interactions in living cells. pacFA acts as a precursor for the biosynthesis of bifunctional lipids. Proteins in contact with the bifunctional lipids are then cross-linked by ultraviolet (UV) irradiation of the diazirine ring. Finally, click chemistry is used to label the alkyne with a reporter molecule.
