WebBifunctional "crosslinking" reagents contain two reactive groups, thereby providing a means of covalently linking two target groups. The reactive groups in a chemical crosslinking reagent (Chemical Crosslinking Reagents—Section 5.2) typically belong to the classes of functional groups—including succinimidyl esters, maleimides and … WebAdditionally, targeting ligands can be incorporated in the resulting photoactivatable fluorophores (PAFs) to label selected subcellular components in live cells. Indeed, photoactivatable BODIPYs have already allowed the sub-diffraction imaging of diverse cellular substructures in live cells using PALM and can evolve into invaluable analytical ...
