Description: DSPE-PEG-PDP is one of ruixibio reactive phospholipid PEG derivatives that can react with free thiol groups. DSPE (1,2-distearoyl-sn-glycero-3-phosphoethanolamine) is an 18 carbon phospholipid that is highly hydrophobic. PEG backbone, on the other hand, offers good hydrophilicity and water solubility. PDP (pyridyldisulfide) functionalized DSPE PEG is able to react with free thiol groups to form a disufide bond which can be cleaved by DTT or other disulfide reducing reagents. Reaction between PDP and thiol allows the attachment of DSPE PEG to thiol bearing molecules or particles with high efficiency. Handling and Use: DSPE-PEG-PDP should always be kept in low temperature in dry condition. Prepare fresh solution right before use.Avoid frequent thaw and freezing.
