Pegylated phospholipids are excellent liposome formation materials that can be used for drug delivery, gene transfection and vaccine delivery as well. ruixibio DSPE-PEG-N3 products can be used to prepare pegylated liposome using Click Chemistry. Azide reacts readily with alkyne or cycloocytne in aqueous solution with or without copper catalyst. Pegylation of phospholipids significantly improves the blood circulation time and stability for encapsulated drugs. Cu-free click chemistry with readily synthesized biarylazacyclooctynones. The reaction of azides with strained alkynes, such as cyclooctynes, readily forms a triazole product without the need for a toxic catalyst.
