Polyethylene glycol (PEG) compounds contain a polyether unit, commonly expressed as R1-(O-CH2-CH2)n-O-R2. They are generally biocompatible, non-toxic and stable in both organic and aqueous solutions, and so are extensively used in biological applications, as well as nanotechnology and materials research. Proteins with PEG chain modifications and compounds encapsulated in PEG liposomes exhibit a longer half-life in vivo than their non-PEGylated counterparts, a phenomenon known as PEG shielding. Functionalised PEG lipids and phospholipids can be used for protein-PEG conjugation. Uses: Activated peg derivatives can be used to modify peptides, proteins, or in other bioconjugation applications. pegylated materials have found broad use in drug delivery systems, virology, and immunology, as the incorporation of peg improves pharmacological properties such as increased water solubility, enhanced resistance to degradation (protein hydrolysis), increased circulation half-life, and reduced antigenicity. in addition to pegylation, activated peg derivatives can also be used to form networks for tissue engineering or drug delivery applications, depending on the architecture and reactivity. Group: Poly(ethylene glycol) and poly(ethylene oxide).
Fmoc-NH-PEG10-CH2CH2COOH is a derivative of polyethylene glycol (PEG) that has been modified with a terminal carboxylic acid group and a base-labile 9-Fluorenylmethoxycarbonyl (Fmoc) protecting group. PEG is a biocompatible and highly hydrophilic polymer that is widely used in various biomedical applications due to its excellent solubility, low toxicity, and resistance to protein binding. The addition of a carboxylic acid group to PEG improves its water solubility and allows for conjugation to amino-containing molecules, such as peptides or proteins. The Fmoc protecting group is widely used in solid-phase peptide synthesis to protect the N-terminal amine group of amino acids from undesired side reactions during chain assembly. Uses: Fmoc-nh-peg10-ch2ch2cooh has a wide range of applications in scientific experiments, including drug delivery, diagnostics, and imaging. its hydrophilic and biocompatible nature makes it an ideal polymer for the synthesis of nanoparticles or micelles that can carry hydrophobic drugs and improve their solubility and bioavailability in biological systems. its carboxylic acid group can also be used fo.
