PEG

Lipoamide-PEG11-Mal contains a lipoic acid group and a maleimide group moiety. The maleimide group will react with a thiol group to form a covalent bond, enabling the connection of biomolecule with a thiol. Lipoic acid contains two sulfur atoms (at C6 and C8) connected by a disulfide bond and is thus considered to be oxidized although either sulfur atom can exist in higher oxidation states. The hydrophilic PEG linker increases the water solubility of the compound. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

DSPE-PEG12-Mal is a PEG linker containing DSPE and maleimide moieties. The hydrophobic properties of the DSPE allow for the encapsulation and congregation of other hydrophobic drugs. The DSPE-PEGs have been FDA approved for medical applications. The maleimide group will react with a thiol group to form a covalent bond, enabling the connection of biomolecule with a thiol. The hydrophilic PEG linker increases the water solubility of the overall compound allowing for the delivery of the drug. Reagent grade, for research purpose.
