The application of polyethylene glycol (PEG) to electron microscopy
The cytoplasm of cells from a variety of tissues has been viewed in sections (0.25-1 micrometers) devoid of any embedding resin. Glutaraldehyde- and osmium tetroxide-fixed tissues were infiltrated and embedded in a water-miscible wax, polyethylene glycol (PEG), and subsequently sectioned on dry glass or diamond knives. The PEG matrix was removed and the sections were placed on Formvarcarbon-pol...
متن کاملImmunogenicity of Polyethylene Glycol (PEG)
Covalent attachment of polyethylene glycol (PEG) to active proteins (PEGylation technology) successfully generated several FDA-approved compounds, including four blockbusters, which are considered non immunogenic. However, PEG antibodies and intolerance to the infusion were reported in some patients with gout treated with pegloticase, a PEG-uricase recently approved by the FDA (Food and Drug Ad...
متن کاملInterfacial Properties of Polyethylene Glycol/Vinyltriethoxysilane (PEG/VTES) Copolymers and their Application to Stain Resistance
In this study, polyethylene glycol (PEG) and vinyltriethoxysilane (VTES) were used in different proportions to produce a series of PEG-VTES copolymers. The copolymer molecular structures were confirmed by FTIR spectroscopy. In addition, their surface activities were evaluated by evaluating the surface tension, contact angle, and foaming properties. The results showed that these surfactants exhi...
متن کاملSafety Evaluation of Polyethylene Glycol (PEG) Compounds for Cosmetic Use
Polyethylene glycols (PEGs) are products of condensed ethylene oxide and water that can have various derivatives and functions. Since many PEG types are hydrophilic, they are favorably used as penetration enhancers, especially in topical dermatological preparations. PEGs, together with their typically nonionic derivatives, are broadly utilized in cosmetic products as surfactants, emulsifiers, c...
متن کاملLow Volume Polyethylene Glycol (PEG) Plus Ascorbic Acid, a Valid Alternative to Standard PEG
Adequate bowel preparation is essential to improve colonoscopy quality. Inadequate bowel preparation may result in lower colonoscopy completion rate, longer duration of colonoscopy, and lower diagnostic yield for polyps. Polyethylene glycol (PEG) has been shown to be safe and effective, and thus regarded as the gold standard for bowel preparation before colonoscopy. However, the standard PEG re...
