Homobifunctional Carboxyl Reactive Monoprotected

Homobifunctional Carboxyl-Reactive Monoprotected Uniform PEG Cross-Linkers are PEG-based molecules featuring two identical carboxyl-reactive groups—such as amines or hydrazides—where one end is temporarily protected to allow controlled, stepwise conjugation. This design enables selective activation and reaction with one carboxyl-containing molecule before deprotecting the second site for targeted bioconjugation. The uniform PEG backbone ensures consistent solubility, spacing, and biocompatibility, making these linkers ideal for constructing well-defined bioconjugates, drug delivery systems, and functional biomaterials.
