Description

m-PEG5-CH2CH2COOH features a five-unit polyethylene glycol chain linked to a terminal carboxylic acid group via a flexible ethylene spacer. This amphiphilic structure enables efficient conjugation in bioconjugation workflows while maintaining solubility and stability under standard conditions.

Application

m-PEG5-CH2CH2COOH serves as a versatile bifunctional linker for conjugation workflows, combining the solubility and stability of a PEG5 spacer with a reactive carboxylic acid group. It facilitates efficient amide bond formation under standard coupling conditions and is well-suited for site-specific modification of peptides, proteins, and biomolecules. The hydrophilic PEG chain minimizes non-specific binding, while the terminal carboxylic acid enables straightforward functionalization in aqueous or mixed solvents.
