Medchemexpress LLC DBCO-NHCO-S-S-NHS ester | 96.0% | 565.66 | C28H27N3O6S2 | 25 MG
DBCO-NHCO-S-S-NHS ester is a cleavable antibody-drug conjugate (ADC) linker and click-chemistry reagent containing a DBCO moiety. It is designed to couple to amines via the NHS ester and to react with azide-bearing molecules through strain-promoted alkyne-azide cycloaddition (SPAAC); the disulfide (S-S) bond provides a reducible, cleavable linker for payload release.
- cleavable disulfide linker for reductive release
- n-hydroxysuccinimide (nhs) ester for amine coupling
- dbco group enables copper-free spaac click chemistry with azides
- solid, white to off-white appearance for easy handling
- available in small research pack sizes (including 25 mg)
- storage: powder at -20°C; in solvent stability at -80°C (6 months) or -20°C (1 month)
