Japanese name: ADCクエンチ試薬(NAC・NEM)

ADC quench reagents cap the excess drug and maleimide left after conjugation and stop the reaction, in the termination step of ADC manufacturing. N-acetylcysteine (NAC) and N-ethylmaleimide (NEM) are typical. Because the point at which residual reactivity is suppressed affects the reproducibility of the drug-to-antibody ratio (DAR), buyers choose by compatibility with the reaction system. Here you will find NAC, NEM and related quench reagents by maker.
