WebMay 7, 2014 · When PEG [ H- (O-CH 2 -CH 2) n -OH ] is added to a DNA solution in saturating condition, DNA forms large random coils. Adding this hydrophilic molecule with the right concentration of salt (Na+) causes DNA to aggregate and precipitate out of solution from lack of solvation (1, 2). Too much salt and you’ll have a lot of salty DNA, too little ... WebChemically it is a polyether, and, more generally speaking, it's a polyalkylene glycol (PAG) H S Code 3907.2000. The term polypropylene glycol or PPG is reserved for polymer of low- to medium-range molar mass when the nature of the end-group, which is usually a hydroxyl group, still matters.

What is Polyethylene Glycol (PEG)? - News-Medical.net
The first step of the PEGylation is the suitable functionalization of the PEG polymer at one or both ends. PEGs that are activated at each end with the same reactive moiety are known as "homobifunctional", whereas if the functional groups present are different, then the PEG derivative is referred as "heterobifunctional" or "heterofunctional". The chemically active or activated derivatives of the PEG polymer are prepared to attach the PEG to the desired molecule.
