Poly(ethylene glycol) (PEG) is a synthetic, hydrophilic, biocompatible polymer with widespread use in biomedical and other applications. PEGs are synthesized using a ring-opening polymerization of ethylene oxide to produce a broad range of molecular weights and molecular weight distributions ...
Cells in the body do not grow as isolated entities attached to a flat surface. They reside in a hydrated extracellular matrix, where they continuously experience spatial confinement, material stiffness, adhesion signals, nutrient diffusion, enzymatic degradation, and changes in growth factors. ...
Biomaterial scaffolds commonly used in tissue engineering and cell biology research are often homogeneous: they have uniform composition, uniform stiffness, and uniformly distributed signaling molecules. In real tissues, however, the cellular microenvironment is highly organized.
Polyethylene glycol (PEG) is a hydrophilic polymer composed of repeating –CH₂–CH₂–O– units. Owing to its excellent water solubility, low toxicity, low immunogenicity, and good biocompatibility, pharmaceutical-grade PEG has been widely used in injectable formulations, sustained/controlled-release ...
Polyethylene glycol (PEG) is a family of linear polyether polymers produced by the stepwise addition polymerization of ethylene oxide with water or ethylene glycol.
Poly(ethylene glycol) (PEG) is a widely used hydrophilic polymer that is commonly employed for the covalent modification of proteins, peptides and small-molecule drugs. By introducing PEG chains onto drug molecules or the surfaces of delivery carriers (PEGylation), their physicochemical ...
Aminooxy PEG Linkers can be used in bioconjugation through the reaction of the aldehyde group with aminooxy to form aldoxime. It is much more stable than hydrazone and imine. In most of cases, it can be used directly without reduction while hydrazine and imines bond normally need be reduced to ...
PEG Ald reagents can be used in bioconjugation through the reaction of the aldehyde group with aminooxy to form aldoxime. It is much more stable than hydrazone and imine. In most of cases, it can be used directly without reduction while hydrazine and imines bond normally need be reduced to form ...
SPDP-PEG crosslinkers enable protein conjugations via amine-to-amine or amine-to-sulfhydryl crosslink. The polyethylene glycol (PEG) spacer arms confer great solubility in the reaction media. SPDP-PEG crosslinkers are best dissolved in organic solvent to make the stock solution. before adding ...
The PEG PFP Ester is a class of PEG labeling reagents that react with primary and secondary amines primary amines to form amide bonds. The pentafluorophenyl (PFP) ester is less subject to hydrolysis than NHS esters, resulting in more efficient reactions. PEG PFP Ester must first be dissolved in ...
Thiol PEG is a thiol-terminated polyethylene glycol (PEG)-containing reagent with either a methyl ether, hydroxyl or carboxylic acid group at the other end. These reagents have defined molecular weights and spacer lengths and are used for modifying surfaces such quantum dots, self-assembled ...

When considering PEGylation for a protein drug, how do you decide what PEGylation chemistry to use?
Can nanoparticles be used for oral drug delivery?
In the field of tissue engineering and regenerative medicine, the design of biomaterial scaffolds that can reproduce the complex extracellular nature of living tissues in three dimensions is a challenging requirement. Hydrogels are a widely studied and developed class of synthetic extracellular ...
Biotechnology fields such as tissue engineering and drug delivery continue to grow with the increasing demand for diverse functional biomaterials. For decades, research in polymeric biomaterials has focused on testing the biocompatibility of polymers developed for other applications or their ...
Bioorthogonal chemistry refers to a series of reactions that occur in a biological environment without affecting biomolecules or interfering with biochemical processes. For this purpose, the reaction must meet the following requirements: fast, efficient, and specific. • pH: The reaction must ...
Polyethylene glycol (PEG) linker is a chemical sensing the carrier of polyethylene glycol (PEG), due to its solubility in water and non-immunogenicity. In the field of scientific research, it is widely used in chemical coupling, drug delivery, nanoparticles functionalized modifications and ...
Poly(ethylene glycol) (PEG) is a synthetic, hydrophilic, biocompatible polymer with widespread use in biomedical and other applications. PEGs are synthesized using a ring-opening polymerization of ethylene oxide to produce a broad range of molecular weights and molecular weight distributions ...
