Uniform mPEG Modifiers

Payload Delivery Linkers and Modifiers | Uniform mPEG Modifiers

Methoxy PEG (mPEG) modifiers are monofunctional PEG molecules capped with a methoxy (-OCH₃) group, which acts as a steric stabilizer to prevent further reactivity. These modifiers reduce non-specific binding, enhance surface properties, and improve biocompatibility in biological applications. Vector Laboratories offers high-purity mPEG modifiers designed for surface modification, blocking, and conjugation. With hydrophilic properties and low immunogenicity, these PEGs minimize background noise and improve assay precision. Ideal for proteins, antibodies, nanoparticles, and metal surface modifications, our mPEGs deliver consistent, reliable performance to support your research.
