Crosslinking reagents in Applications
Bifunctional crosslinkers are molecules that contain two functional groups, either identical, or different, for the synthesis of conjugates of biomolecules.
Lumiprobe offers a range of bifunctional crosslinker molecules that contain various terminal reactive groups flanking different linkers, including short alkyls, and longer polyethylene glycols (PEGs).
