DSPE-PEG-Biotin,385437-57-0,磷脂-聚乙二醇-生物素用于生物分子的检测和纯化

磷脂-聚乙二醇-生物素(DSPE-PEG-Biotin),CAS:385437-57-0,所属分类:Biotin PEG DSPE PEG,MW:2000。质量控制在95%+,一般主要用于科研实验使用。DSPE-PEG-Biotin的分子量可定制,DSPE-PEG5-Biotin、DSPE-PEG3.4-Biotin、DSPE-PEG1-Biotin1k等。


DSPE - PEG - Biotin is a kind of Biotin and DSPE phospholipids functional lecithin PEG derivatives. DSPE (1, 2-2 stearoyl - sn - glycerol - 3 - ethanolamine phosphate) is a kind of highly hydrophobic 18 carbon phospholipids.


On the other hand, the main chain of the PEG has good hydrophilicity and solubility in water. Biotin is a kind of common bioactive molecules, of avidin or chain mildew avidin combination of high affinity.


生物素/链霉亲和素系统被广泛应用于蛋白质、核酸等生物分子的检测和纯化。生物素修饰的DSPE-PEG可与脂质体等纳米粒子结合,可用于亲和素或链霉亲和素结合底物的靶向检测。


它溶于水和缓冲液等有机溶剂,较少溶于醇、甲苯,不溶物乙醚。磷脂-聚乙二醇-生物素需在-20°冷冻、避光、干燥储藏。此类产品应现配现用,取用后充入惰性气体并及时放入冰箱。
