Application

Poly(ethylene glycol) has been used to develop a method for efficient transformation of Brevibacterium lactofermentum protoplasts with plasmid DNA. It has been used as a fusion agent to fuse spleen cells with the myeloma cell line SP2/0.

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.
