Uniform PEG Cross-Linkers are precisely synthesized polyethylene glycol-based reagents with defined chain lengths and reactive end groups for controlled bioconjugation. These cross-linkers provide consistent spacer lengths that improve solubility, reduce steric hindrance, and enhance flexibility between linked biomolecules.
Their uniformity ensures reproducible conjugate properties, critical for applications such as protein labeling, drug delivery, and biomaterial engineering. Reactive groups on both ends enable covalent bonding to target molecules like proteins, peptides, or nanoparticles.
Uniform PEG cross-linkers are widely used to create stable, functional bioconjugates with predictable behavior in biological systems.
The range of uniform PEG cross-linkers sold by Vector Labs includes heterobifunctional hydrazone/oxime bond-forming reagents, homobifunctional amine-reactive (both monoprotected and unprotected), thiol-reactive, homotetrafunctional thiol-reactive, heterobifunctional amine- and thiol-reactive, as well as homobifunctional carboxyl-reactive (monoprotected and unprotected) cross-linkers, providing versatile tools for precise and stable bioconjugation and cross-linking applications.
