WebPrecipitation by polyethylene glycol (PEG) is a common method to concentrate and capture large proteins as the first step of a purification process. The phenomenon could be interpreted through the theories of attractive depletion (Asakura and Oosawa, 1958) and excluded volume (Iverius and Laurent, 1967, Polson, 1977). WebPoly (Ethylene Glycol) Functionalized Graphene Oxide in Tissue Engineering: A Review on Recent Advances. Abstract: Owing to the unique physical, chemical, mechanical and electrical properties, graphene and its derivatives have been extensively researched for diverse biomedical applications including in tissue engineering since the past decade.

WebMar 1, 2024 · PEG is one of the most commonly used polymers for extracting proteins and is widely used as a precipitant and a crystallizer for the precipitation and crystal formation of proteins (Mine and D’Silva, 2008; Du et al., 2015).According to current theories, the precipitation of the protein using PEG is mainly based on the “volume exclusion effect” …
WebJan 20, 2024 · Polyethylene glycol (PEG)-induced protein precipitation is often used to extrapolate apparent protein solubility at specific formulation compositions. The procedure was used for several fields of application such as protein crystal growth but also protein formulation development. WebPolyethylene glycol is a biologically inert, non-immunogenic chemical that confers greater water solubility to proteins, labeling tags and crosslinkers with which it is incorporated as constituent chemical group. This page provides a brief introduction to the use and types of PEG reagents available to protein biology researchers.
