DSPE PEG Maleimide, DSPE-PEG-M

Micro- and Mid-Scale Maleimide-Based Conjugation of Cytotoxic Drugs to Antibody Hinge Region Thiols for Tumor Targeting

and stability. Here we elaborate detailed protocols using maleimide-based chemistry for the conjugation to reduce hinge disulfides in antibodies by several cytotoxic drugs. We present a method for the initial characterization of the reduction/alkylation reaction

Angiogenic Vessel-Targeting DDS by Liposomalized Oligopeptides

of PEGylated liposomes, we synthesized a novel lipid derivative of the peptide, distearoylphosphatidylethanolamine–polyethyleneglycol–APRPG (DSPE–PEG–APRPG). The lipid derivative of APRPG peptide is expected to be readily incorporated into liposomal membrane

PEGylation of Antibody Fragments for Half-Life Extension

of polyethylene glycol (PEG) chain to protein using PEGylation technology. The most suitable approach employs PEG-maleimide attachment to cysteines, either to the free hinge cysteine or to C-terminal cysteines involved in interchain disulfide linkage of the heavy
