Background

BOC Sciences provides high purity PEG raw materials for chemical, biological, medical, industrial and commercial uses. Our products range in molecular weight from 200 to 20,000 dalton, providing flexibility in the selection of properties to meet the requirements of many different applications.

What is PEG

Different molecular weight polyethylene glycol has different morphology.

Polyethelene glycol (PEG) is a synthetic, hydrophilic, biocompatible polyether, which is consist of a (−O−CH2−CH2−) backbone. PEG is widely used in various fields, from industrial manufacturing to medicine. Its structure is commonly expressed as H−(O−CH2−CH2)n−OH. Depending on the molecular weight, PEG is also known as polyoxyethylene (POE) or polyethylene oxide (PEO). PEGs can be synthesized in linear, branched, Y-shaped, or multi-arm geometries. PEGs can be activated by replaing the terminal hydroxyl end group with various reactive functional end groups enabling crosslinking and conjugation chemistries.

Application of PEG

PEG is a kind of liquid or a low-melting solid obtained by ethylene oxide polymerization. PEG has a wide range of molecular weights and is widely used in various fields.

Chemical uses	Used as lubricating coating for various surfaces. Used to create high osmotic pressure. Used to passivate microscope slides. Used to preserve objects salvaged from underwater. Used to preserve the color of painting. Used as heat transfer fluid in electronic testers. Used as the polar stationary phase of gas chromatography. Used as an internal calibration compound in mass spectrometry experiments.
Biological uses	Used as a crowding agent in vitro to simulate highly crowded cellular conditions. Used as a precipitant for plasmid DNA isolation and protein crystallization. Used for cell fusion. Used for virus concentratation. Used to coat gene therapy vectors to protect them from inactivation by the immune system. Used to package siRNA for in vivo use. Used as a potentiator to enhance detection of antigens and antibodies in blood banking. Used in the functioning ion channels diameter studies to block ion channel conductance.
Medical uses	Widely used in pharmaceutical formulations. Used as the basis of a number of laxatives. Used as an excipient in many pharmaceutical products. Possibly used to fuse axons. Used to synthetic lubricant. Used as solvent to prepare water-soluble drugs. Used to modify medical polymer materials. Used as linkers for antibody-drug conjugates (ADCs). Used as a surface coating on nanoparticles to improve systemic drug delivery. Frequently used in many biomedical applications, including but not limited to bioconjugation, drug delivery, surface functionalization and tissue engineering.
