Description

Application

This is a cathepsin cleavable linker used in bioconjugation, specifically in the construction of antibody drug conjugates (ADC & Bioconjugation).

Features and Benefits

Fmoc-Val-Cit-PAB-PNP is a cleavable ADC linker used in the synthesis of antibody-drug conjugates (ADC). The Val-Cit is specifically cleaved by cathepsin B. Fmoc-Val-Cit-PAB-PNP has superior plasma stability comparable to that of non-cleavable linkers.
