Bis-PEG21-NHS ester

Catalog No.: A42679
ADC/PROTAC Linker
Bis-PEG21-NHS ester is a polyethylene glycol (PEG) based linker with a primary mechanism as a cleavable ADC and PROTAC linker. This compound facilitates the synthesis of PROTACs and antibody-drug conjugates (ADCs) by providing a stable yet versatile connecting moiety. Its unique properties support targeted drug delivery and enhance the specificity of therapeutic applications in chemical biology research.
