Product Description
Polyethylene glycol (PEG)：It is a polyether compound with many applications from industrial manufacturing to medicine. PEG is also known as polyethylene oxide (PEO) or polyoxyethylene (POE), depending on its molecular weight. The structure of PEG is commonly expressed as H−(O−CH2−CH2)n−OH.                                                                                                                                                                                                                                                Application

1.Chemical uses

PEG is the basis of a number of laxatives. Whole bowel irrigation with polyethylene glycol and added electrolytes is used for bowel preparation before surgery or colonoscopy.PEG is also used as an excipient in many pharmaceutical products.When attached to various protein medications, polyethylene glycol allows a slowed clearance of the carried protein from blood.

2.Medical uses

PEG is often used (as an internal calibration compound) in mass spectrometry experiments, with its characteristic fragmentation pattern allowing accurate and reproducible tuning.

PEG derivatives, such as narrow range ethoxylates, are used as surfactants.

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.
