Product Description:
Bis-PEG11-NHS Ester is widely used in bioconjugation and crosslinking applications. It enables the covalent attachment of two biomolecules, such as proteins, peptides, or antibodies, by reacting with primary amine groups to form stable amide bonds. The long, hydrophilic PEG spacer (11 units) enhances solubility and reduces aggregation in aqueous solutions, while also minimizing steric hindrance between linked molecules.
This reagent is particularly useful in the development of antibody-drug conjugates (ADCs), diagnostic probes, and functionalized nanoparticles. Its bifunctional structure allows for controlled spacing between molecules, which is critical in maintaining biological activity after conjugation. Additionally, it is employed in surface modification of biosensors and medical devices to improve biocompatibility and reduce non-specific binding.
Due to its water-soluble nature and selective reactivity, Bis-PEG11-NHS Ester is a preferred choice in preparing well-defined conjugates for research, therapeutic, and diagnostic applications.
