PEGylated SPDP Crosslinkers, Heterobifunctional, Pierce™

Supplier: Thermo Fisher Scientific

Cross linkers are used for the identification of near-neighbour protein relationships and ligand-receptor interactions. Homobifunctional, amine-reactive NHS esters or imidates, and heterobifunctional, amine-reactive, photoactivatable phenyl azides are the most commonly used crosslinkers for these applications.
