Lipids & Polymers

4arm-PEG-Maleimide, MW 5,000 is a thiol reactive multiarm PEG polymer. Maleimides react with thiols or sulfhydryl-containing molecules at pH 6.5 to 7.5 via formation of stable thioether bond. The hydrophilic PEG chain increases the water solubility of the compound in aqueous media. Reagent grade, for research use only.

m-PEG-Mal, MW 1,000 is a PEG-based crosslinking agent that contains a thiol reactive functional group. The maleimide group can react with thiols between pH 6.5 to 7.5 to form a stable thioether bond. Reagent grade, for research use only.

PEG-bis-SPDP, MW 1,000 is a water soluble PEG polymer with two SPDP moieties. It is reactive with thiol to form disulfide molecules. Reagent grade, for research use only.

PEG-bis-SPDP, MW 5,000 is a water soluble PEG polymer with two SPDP moieties. It reacts with thiol groups to create disulfide molecules. Reagent grade, for research use only.
