三、產(chǎn)品簡介

DSPE-PEG-MAL是反應(yīng)性磷脂PEG試劑之一，可以與巰基（硫醇，-SH）反應(yīng)，DSPE（1,2-二硬脂酰基-sn-甘油3-磷酸乙醇胺）是一種高度疏水的飽和18C磷脂。另一方面，PEG接頭（聚乙二醇）具有良好的親水性和水溶性，馬來酰亞胺官能的DSPE PEG對衍生自各種分子的巰基/硫醇基團(tuán)具有出色的反應(yīng)性，馬來酰亞胺和硫醇之間的反應(yīng)在中性pH下容易進(jìn)行。

Maleic imide PEGDSPE liposome is liposome and other lipid nanoparticles on the surface of the antibodies, peptides or other ligand spatialization of one of the most commonly used the reactivity of phospholipids. Polyethylene glycol (PEG) of phospholipids have longer cycle time of blood and to the higher stability of the encapsulated drug, this product has high purity, excellent chemical reactivity and quantity of the various points of mercaptan reactive maleic imide phospholipids PEG products integrated products. The lipid PEG conjugated content have excellent amphiphilic, for the small molecule and the big drug preparation and transport advantages.Phospholipids PEG maleic imide (DSPE - PEG - Mal) can be used to modify proteins, peptides and other materials containing hydrophobic base or small molecules, maleic imide and hydrophobic base in PH6.5-7.5 it's easy to form stable sulfur wake key, (DSPE) conjugate polyethylene glycol (PEG) is a phospholipids and polyethylene glycol (PEG) combined with hydrophilic and hydrophobic. Polyethylene glycol lecithin liposome formation of high quality material, can be used for drug delivery, gene transfection and vaccine delivery, polyethylene glycol (peg), phospholipid encapsulated drugs can significantly improve the blood circulation time and stability, these materials can also be used for targeted drug delivery by modifying the ligands such as antibodies, peptides with the target surface.
