General description

An oligomer of polyethylene glycol, tetra (ethylene glycol) (TEG) is a transparent, colorless, odorless, low volatility, hygroscopic liquid soluble in ethyl alcohol and very soluble in water.

Application

Used for the synthesis of tetraethylene glycol metha acrylate monomer.[1]

Glow discharge plasma deposition of TEG renders surfaces resistant to protein adsorption and cellular attachment.[1]

Caution

Do not confuse with glycofurol, which is also sometimes called tetraglycol.

    Degradable Poly(ethylene glycol) Hydrogels for 2D and 3D Cell Culture

    Progress in biotechnology fields such as tissue engineering and drug delivery is accompanied by an increasing demand for diverse functional biomaterials. One class of biomaterials that has been the subject of intense research interest is hydrogels, because they closely mimic the natural environment of cells, both chemically and physically and therefore can be used as support to grow cells. This article specifically discusses poly(ethylene glycol) (PEG) hydrogels, which are good for biological applications because they do not generally elicit an immune response. PEGs offer a readily available, easy to modify polymer for widespread use in hydrogel fabrication, including 2D and 3D scaffold for tissue culture. The degradable linkages also enable a variety of applications for release of therapeutic agents.
