应用简介：   

DSPE-PEG-COOH是芃硕生物一种带活性基团的磷脂PEG衍生物，DSPE和聚乙二醇结合具有亲水性和疏水性，聚乙二醇磷脂脂质体形成上等材料，能够用于药输送、基因转染和疫苗传递。聚乙二醇化磷脂可以明显的改善血循环时间和稳定封装药。羧基（-COOH）可以和氨基形成稳定的酰胺键，也可以和羟基发生酯化反应。

端基取代率：

DSPE：≥95%

-COOH：≥95%

溶解性：DCM,DMSO

取用保存：现配现用，将产品从冰箱中取出，置于干燥器中缓慢升至室温，打开瓶盖，取用。取用后充入惰性气体，封口膜封口，拧紧瓶盖装入自封袋，及时放入冰箱。

注意事项：DSPE-PEG-COOH因为DSPE的原因，水溶性不好，PEG分子量5000以及以上水溶性会好一些。

备注：芃硕生物所有产品仅用于的科学研究，不能用于人体用途。更多详情请咨询芃硕生物！
