m-PEG2-acid features a short, hydrophilic polyethylene glycol spacer flanked by a reactive carboxylic acid group, enabling efficient conjugation in bioconjugation workflows. This bench-stable reagent facilitates site-specific attachment to amine-containing biomolecules while maintaining solubility in aqueous systems.
m-PEG2-acid serves as a versatile, bench-stable linker for conjugation and macrocyclization workflows. Its terminal carboxylic acid enables efficient amide bond formation with amines under standard coupling conditions, while the short PEG2 spacer provides enhanced solubility and reduced aggregation. Ideal for peptide-drug conjugates and oligonucleotide modifications, it facilitates purification via ion-exchange chromatography and offers predictable behavior in aqueous environments.
