Product profile
DSPE is classified as phosphatidylethanolamines (Formula C41H82NO8P; molecular weight 748.10).
DSPE provides a reactive functional group for conjugation, immobilization or linker-extension studies.
For DSPE, functional handles may require orthogonal protection, pH control and rapid purification to avoid hydrolysis, oxidation or cross-reaction.
