What is polyethylene glycol monomethyl ether?

What is polyethylene glycol monomethyl ether?

Poly(ethylene) glycol monomethyl ethers (Peg-mmes) are a series of methyl substituted poly(ethylene) glycols that have been used with some success in the crystallization of a number of hydrophobic proteins. We suggest that these modified Peg-mmes should be regularly used in screening for crystallization.

What is propylene glycol methyl ether used for?

Propylene Glycol Monomethyl Ether is a colorless liquid with a sweet Ether-like odor. It is used in cleaning solutions and as a solvent for coatings, acrylics, dyes, inks and stains.

What is mPEG chemical?

Poly(ethylene glycol) methyl ether (mPEG) is a hydrophilic polymer that is used to control the flexibility of a composite. mPEG can be used for a variety of applications such as drug delivery, tissue engineering, and other biological uses.

For what polyethylene glycol method is used?

Polyethylene glycol mediated DNA uptake is a direct gene transfer method that utilizes the interaction between PEG, naked DNA, salts and the protoplast membrane to effect transport of the DNA into the cytoplasm.

Is propylene glycol monomethyl ether an alcohol?

Methoxy propanol (also known as propylene glycol monomethyl ether, 1-methoxy-2-propanol, PM, and PGME), is a colourless liquid that is soluble in water and is highly flammable. It is a methoxy alcohol derivative and has a formula of C4H10O2.

Is Methoxypolyethylene glycol the same as polyethylene glycol?

The methoxy polyethylene glycols (MPEGs), also referred to as polyethylene glycol methyl ethers, are high molecular weight polymers similar in structure and nomenclature to the polyethylene glycols.

What is polyethylene glycol in biotechnology?

Abstract. Chemical modification of proteins and other bioactive molecules with polyethylene glycol (PEG) or its derivatives (PM) can be used to tailor molecular properties to particular applications, eliminating disadvantageous properties or conferring new molecular functions.

What is PEG in chemistry?

PEG is the common abbreviation for polyethylene glycol – or, more properly, poly(ethylene glycol) – which refers to a chemical compound composed of repeating ethylene glycol units.

What is glycol made of?

glycol, any of a class of organic compounds belonging to the alcohol family; in the molecule of a glycol, two hydroxyl (―OH) groups are attached to different carbon atoms. The term is often applied to the simplest member of the class, ethylene glycol.
