试剂简介：

DSPE-PEG-CY5.5是一种水溶性染料，偶联到具有亲水磷酸盐头和疏水脂尾的PEG聚合物上。Cy5.5标记的PEG衍生物从其蓝色和强荧光性可以很容易地被追踪到。该染料的吸光度和发射量与Cy5.5荧光团相同。该聚合物在水中可自组装形成脂质双分子层。该磷脂聚乙二醇可作为medicinal纳米载体，用于营养物质和Therapeutic drugs的管理，如mRNA或DNA疫苗中的脂质体。

DSPE-PEG-CY5.5 is a water-soluble dye that is coupled to PEG polymers with hydrophilic phosphate heads ａnd hydrophobic lipid tails. Cy5.5 labeled PEG derivatives can be easily traced from their blue ａnd strong fluorescence. The absorbance ａnd emission of this dye are the same as the Cy5.5 fluorescent group. The polymer can self-assemble into a lipid bilayer in water. The phospholipid polyethylene glycol can be used as a drug nanocarrier for the management of nutrients ａnd therapeutic drugs, such as liposomes in mRNA or DNA vaccines.
