Description:
Preparation Note
Poly(ethylene glycol) dissolves in many organic solvents and is readily soluble in aromatic hydrocarbons. It also slightly dissolves in aliphatic hydrocarbons.
Application
Poly (ethylene glycol) can be used as a test compound utilized in the overproduction and purification of recombinant Lactobacillus reuteri LrNDT. It can also be used for concentrating the mutants with lower secretion levels used in ELISAs for the quantitation of shgp190 and of the LIF/shgp190 complexes.
Biochem/physiol Actions
Polyethylene glycol (PEG) is a condensation polymer of ethylene oxide and water. It enhances the refolding of extracted proteins. This enables characterization of crystallized proteins.
