    N-Succinimidyl bromoacetate

    NHS-Bromoacetate

    		 Biochemical Assay Reagents Infection
    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 .
