peg has been used as the hydrophilic block of amphiphilic block copolymers used to create some polymersomes.

3.biological uses

peg is commonly used as a precipitant for plasmid dna isolation and protein crystallization. x-ray diffraction of protein crystals can reveal the atomic structure of the proteins.

peg is used to fuse two different types of cells, most often b-cells and myelomas in order to create hybridomas.
