Application: Polyethylene glycol 2000 is used in the construction of biomaterials such as biopolymers, micelles and nanostructures.
Biochem/physiol Actions: O-Methyl-O′-succinylpolyethylene glycol 2′000 is a modified monomethoxypolyethylene glycol (mPEG) wherein the hydroxyl groups are succinylated by succinic anhydride. This succinylated mPEG can then be used to synthesize tolerogenic mPEG conjugates of peptides. Tolerogenic peptide conjugates are very effective reagents for obtaining epitope-specific immunosuppression of antibody responses to immunopathogenic sites on multideterminant complex protein antigens.

New Tariffs & Effects on Pricing

Tariff note: As we navigate the current environment of tariff surcharges and mid-year manufacturer price increases, we want to keep you informed. While we have avoided making specific decisions thus far, we anticipate that we will be forced to implement a cost adjustment policy to offset the fees we have already been absorbing. We are committed to transparency and moderation in this process.
