Descrizione generale

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.

Applicazioni

Poly(ethylene glycol) has been used for stress (dehydration) treatment in seedlings of Galegae orientalis. It has been used for the preparation of aqueous two-phase system to study protein diffusion across the interface.

Mechanical stability of epithelia requires firm attachment to the basement membrane via hemidesmosomes. Dysfunction of hemidesmosomal proteins causes severe skin-blistering diseases. Two plakins, plectin and BP230 (BPAG1e), link the integrin α6β4 to intermediate filaments in epidermal hemidesmosomes. Here, we show
