Payload Delivery Linkers and Modifiers

PEG (polyethylene glycol) linkers and coupling reagents are hydrophilic molecular spacers used in drug delivery and bioconjugation, improving solubility, stability, and biocompatibility. These reagents facilitate controlled payload release in applications such as antibody-drug conjugates (ADCs) and targeted therapeutics. Vector Laboratories provides a comprehensive selection of high-purity, single molecular weight PEG products that minimize aggregation and non-specific binding, ensuring consistent, reliable results using proteins, peptides, nanoparticles, antibodies, ADCs, and other biomolecules. The uniform molecular weight of these reagents streamlines identification and purification, making experimental workflows more efficient. Backed by rigorous quality control and scientific expertise, our products enhance conjugation efficiency and advance scientific breakthroughs with confidence.
