三、产品简介

DSPE-PEG-MAL是反应性磷脂PEG试剂之一，可以与巯基（硫醇，-SH）反应，DSPE（1,2-二硬脂酰基-sn-甘油3-磷酸乙醇胺）是一种高度疏水的饱和18C磷脂。另一方面，PEG接头（聚乙二醇）具有良好的亲水性和水溶性，马来酰亚胺官能的DSPE PEG对衍生自各种分子的巯基/硫醇基团具有出色的反应性，马来酰亚胺和硫醇之间的反应在中性pH下容易进行。

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.
