Homotetrafunctional Thiol Reactive

Homotetrafunctional Thiol-Reactive Uniform PEG Cross-Linkers are PEG-based molecules featuring four identical thiol-reactive groups—such as maleimide or vinyl sulfone—arranged symmetrically for multivalent cross-linking of thiol-containing biomolecules. These cross-linkers enable the formation of multiple stable thioether bonds, making them ideal for creating complex, branched, or networked bioconjugates.

The uniform PEG core ensures high solubility, biocompatibility, and spatial separation, supporting applications in hydrogel formation, nanoparticle functionalization, and multivalent drug delivery systems.
