PEGylation is a revolutionary modification of a therapeutic protein, nucleic acid, or small drug molecule by covalently attaching polyethylene glycol (PEG) or a derivative thereof. This makes the molecule more water-soluble, increases bioavailability and reduces immunogenicity or antigenicity. PEGylation service is used to increase the half-life of a drug, allowing it to remain in the body for a longer period of time and thus providing a more sustained therapeutic effect. PEGylation also helps to reduce the toxicity of a drug, as the PEG molecules act as a protective shield, preventing the drug from interacting with other molecules in the body. PEGylation can also be used to improve the pharmacokinetics of drug molecules by controlling their absorption, distribution, metabolism and excretion. Hence, PEGylation is a widely used technology in the pharmaceutical industry and has been used to develop a number of successful drugs.


PEGylation is typically accomplished through a process called conjugation, which involves attaching the PEG molecules to the drug or other molecule. This is usually done through a chemical reaction, such as a condensation reaction, in which the PEG molecules are linked to the drug molecule through a covalent bond.




The PEG molecules can also be attached to the drug molecule through a non-covalent bond, such as hydrogen bonding or electrostatic interactions. Once the PEG molecules are attached to the drug molecule, the drug is said to be PEGylated. ALL Chemistry Inc. offers a full range of PEGylation services to researchers and discovery-stage companies in need of high quality services.
