Cross-Linkers and DSPE Linkers

Vector Laboratories offers an extensive suite of cross-linking reagents and DSPE-functionalized linkers designed for covalent modification, labeling, and stabilization of biomolecules in research and diagnostic workflows. These reagents facilitate precise conjugation between proteins, nucleic acids, glycans, and surfaces via reactive functional groups or orthogonal chemical handles. The collection spans classical, hetero/homobifunctional, click-compatible, and PEG-based linkers—providing flexibility for both standard and bioorthogonal chemistry applications.

Categories in the Cross-Linker and DSPE Linker portfolio area include Classical Cross-Linkers, Click Chemistry-Compatible Linkers, DSPE Linkers, and Uniform PEG Cross-Linkers.

Our Cross-Linker and DSPE Linker portfolios are engineered to enable precise and customizable conjugation strategies, whether for simple protein labeling, nanoparticle modification, or advanced Click Chemistry applications. With options spanning classical covalent chemistry and modern bioorthogonal systems, these tools support a wide spectrum of research needs in chemical biology, drug delivery, diagnostics, and molecular engineering.
