Description
- General description: Poly(ethylene glycol) (PEG) is a non-ionic hydrophilic polymer and is available in different molecular weights. It helps in the purification and crystal growth of proteins and nucleic acids. PEG and dextran together result in aqueous polymer two phase system, which is required for the purification of biological materials. PEG also interacts with cell membrane, thereby allowing cell fusion.[1][2]
- Application: Poly(ethylene glycol) has been used for stress (dehydration) treatment in seedlings of Galegae orientalis.[3] It has been used for the preparation of aqueous two-phase system to study protein diffusion across the interface.[4]
- Other Notes: Fractional precipitation of proteins[5]; Protoplast fusion[6]; In virus purification[7]; Electroblotting of proteins on agarose gel containing PEG and antibodies[8]
