CD Bioparticles provides high quality activated homobifunctional polyethylene glycol derivatives with high purity and low polydispersity.
Homobifunctional Linear PEGs are monodisperse polyethylene glycol (PEG) linkers with identical functional ends. These are commonly used for biological conjugation and cross-linking of proteins. We offer homobifunctional linear PEGs with different molecular weights that can attach two identical functional groups such as acid, acrylamide, acrylate, aldehyde, alkyne, amine, aminooxy, azide, benzamide, bio Vine, boc protected amines, coonhs, carboxymethyl, epoxy, folic acid, hydroxyl, iodoacetyl, isocyanate, maleimide, methacrylamide, methacrylate, nhs, nitrobenzene carbonate Esters, ortho-pyridine disulfide (opss), pentafluorophenyl (pfp) esters, silanes, thiols, tosylate, trans-cyclooctene and vinyl sulfone.
Our homobifunctional PEG derivatives have many applications as crosslinkers, including PEGylation of proteins and peptides, or nanoparticles and surface modification. Homobifunctional PEG derivatives have the general structure: X-PEG-X, where X is a functional reactive group.
