| Details | DSPE-PEG(2000) Maleimide is a linear heterobifunctional PEGylation reagent with a DSPE phospholipid and a maleimide, providing a thiol or cysteine reactive maleimide group during PEGylated liposome or micelle preparation. PEG provides stealth property, extends circulation half-life, and reduces non-specific protein binding or cell adhesion. The reactive maleimide bioconjugates targeting molecules including antibody, aptamer, protein, and peptide. |
| Percent Composition | C 56.76%, H 9.29%, N 1.90%, O 31.00%, P 1.05% |
