Homobifunctional Amine Reactive Monoprotected

Homobifunctional Amine-Reactive Monoprotected Uniform PEG Cross-Linkers are PEG-based molecules containing two identical amine-reactive groups (such as NHS esters), with one end temporarily protected to allow sequential or controlled conjugation. This design enables selective attachment of one molecule first, followed by deprotection and reaction of the second amine-reactive site, offering precision in bioconjugation workflows. The uniform PEG backbone enhances solubility, biocompatibility, and structural predictability, making these linkers ideal for creating well-defined protein conjugates, drug carriers, and multifunctional biomaterials.
