Descripción general

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.

Aplicación

Used for the synthesis of tetraethylene glycol metha acrylate monomer.

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

Precaución

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

Intra-articular delivery of therapeutics to modulate osteoarthritis (OA) is challenging. Delivery of interleukin-1 receptor antagonist (IL-1Ra), the natural protein inhibitor of IL-1, to modulate IL-1-based inflammation through gene therapy or bolus protein injections has emerged as a promising therapy for
