Bis-sulfone-PEG-Acid

A dual-functional linker. The sulfonic acid groups in this molecule can form stable covalent bonds with specific sites on biomolecules such as proteins, while the PEG chain provides water solubility and flexibility. The terminal carboxylic acid facilitates further coupling with groups like amino groups, making it widely applicable in bio-conjugation and material surface modification.
