产品说明:

FITC-PEG-DSPE is one of Ponsure fluorescent phospholipid PEG derivatives that can be used for lipid nanoparticle formulation, tracking and detection. DSPE (1,2-distearoyl-sn-glycero-3-phosphoethanolamine) is an 18 carbon saturated phospholipid that is highly hydrophobic. PEG backbone, on the other hand, offers good hydrophilicity and water solubility. Fluorescein labeled DSPE PEG emits strong green fluorescent light at 515 nm upon excited at 495nm. FITC-PEG-DSPE can be easily incorporated into liposome or other lipid or phospholipid nanoparticles. Strong fluorescent signal from FITC allows quick and easy detection and tracking of labeled species. PEG linker between Fluorescein and DSPE offers good water solubility, flexible linker structure and increased stability.

处理以及使用:

FITC-PEG-DSPE 需要一只保存在低温、干燥、避光的条件，使用时一定要注意温差，防止吸潮，纯品保存最佳。

储存条件：

FITC-PEG-DSPE 于-20℃干燥保存.惰性气体保护最佳. 一年之后复测。
