I. [Product Description]
This product is a multifunctional and bifunctional cross-linking agent. Its core structure contains sulfonic acid groups, SPDP active groups, and NHS esters, combining excellent water solubility with controllable coupling properties. As a high-purity organic intermediate, it is widely used for directional modification and stable connection in bioconjugation reactions. Its PEG segment significantly enhances the molecular biocompatibility and the ability to regulate steric hindrance.
