Polyethylene glycol (PEG) is one of the most frequently used polymers for coating nanocarriers to enhance their biocompatibility, hydrophilicity, stability, and biodegradability. PEG is now considered to be among the best biocompatible polymers.

COOH-PEG-COOH is a homobifunctional PEG derivative, generally used to modify proteins, peptides and other substances with amino or other acid-reactive chemical groups. COOH-PEG-COOH can increase solubility and stability and reduce the immunogenicity of …

Product is a thiolated carboxylic-polyethylene . 4α;-sulfanyl—ω carboxy PEG (HS–PEG–COOH) heterobifunctional PEGs with functional end-groups of very different reactivity. HS-PEG-COOH inhibits nonspecific binding to living cells.

Apr 1, 2014 · Monodisperse Fmoc–PEG–COOH with a range of PEG (PEG 2 –PEG 36) are now available commercially (from Quanta Biodesign) and have been used to prepare PEG–peptide conjugates such as PEG–FFKLVFF–COOH.

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 ...

Amino PEG Acid (NH2-PEG-COOH) is one of Nanocs reactive heterobifunctional PEG derivatives that have an amine group on one PEG end and a carboxylic acid group on the other PEG terminus. Amino PEG acid can be used to modify proteins, peptides and other materials via amino or other acid reactive chemical groups.

Carboxylic acid (-COOH) PEG is a derivative of polyethylene glycol that has a carboxylic acid functional group attached to its structure. Carboxylic acid PEG derivatives are commonly used in various applications, including pharmaceuticals, cosmetics, and materials science.

ABSTRACT: A well-defined poly(ethylene glycol) (PEG) possessing a 2-pyridyldithio end group at one end and a carboxyl group at the other end was prepared after chemical modification of the...

Boc-NH-PEG-COOH is a linear heterobifunctional PEG reagent containing carboxyl group and Boc protected amine. It is a crosslinker with a PEG spacer group. Protected amines can be regenerated through weakly acidic conditions, such as TFA or dilute HCl.
