FSK hydrochloride is fluorosulfonyloxybenzoyl-L-lysine, which features a long, flexible aryl fluorosulfate-containing side chain that can reach protein sites inaccessible to covalent conjugation. FSK hydrochloride modifies nanomolecules to target epidermal growth factor receptor (EGFR), resulting in irreversibly bound covalent interactions. Through genetically encoded chemical crosslinking, FSK hydrochloride captures unknown enzyme-substrate interactions in living cells, targets residues other than Cys, and mediates crosslinking at the binding periphery. FSK hydrochloride enables the construction of a bioreactive SuFEx system for generating covalent bonds in various proteins both in vitro and in vivo .

N-Succinimidyl bromoacetate (NHS-Bromoacetate) is a heterobifunctional crosslinking reagent, mainly used to modify the ɛ-amino group of lysine side chains. By covalently linking its bromoacetyl moiety to the ɛ-amino group of lysine in peptidomimetics, N-Succinimidyl bromoacetate enables their conjugation with thiol-modified nanoparticles via thioether bonds. N-Succinimidyl bromoacetate also performs bromoacetylation modification on carrier proteins, which then forms stable thioether bonds with the thiol groups of cysteine in peptides, thus efficiently preparing soluble peptide-protein conjugates with high substitution ratios. N-Succinimidyl bromoacetate can be used to prepare activated Sepharose derivatives for affinity chromatography, protein affinity labeling reagents, and peptide-protein immunogen conjugates with non-immunogenic linkages. N-Succinimidyl bromoacetate is applicable to studies related to HIV-1 infection and glioblastoma multiforme .
