Homobifunctional Thiol Reactive

Homobifunctional Thiol-Reactive Uniform PEG Cross-Linkers are PEG-based molecules with identical thiol-reactive groups—such as maleimide, iodoacetamide, or vinyl sulfone—at both ends, designed to covalently link biomolecules containing free thiol (-SH) groups. These cross-linkers enable the formation of stable thioether bonds between cysteine residues on proteins or other thiol-containing compounds. The uniform PEG spacer provides optimal solubility, flexibility, and biocompatibility, making them ideal for applications in protein cross-linking, drug delivery, and biomaterial engineering.
