Homobifunctional Carboxyl Reactive

Homobifunctional Carboxyl-Reactive Uniform PEG Cross-Linkers are PEG-based molecules with identical reactive groups—such as primary amines or hydrazides—at both ends that selectively form covalent bonds with carboxylic acid groups on biomolecules.

These cross-linkers enable stable amide or hydrazone bond formation, allowing for the coupling of carboxyl-containing proteins, peptides, or other molecules. The uniform PEG spacer imparts solubility, flexibility, and biocompatibility, making them ideal for precise bioconjugation in therapeutic development, biomaterials, and diagnostics.
