To decipher this intricate code, understanding of its assembly, architecture, as well as specific interactors of these Ub/UbL hybrid chains are important, warranting the development of suitable reagents. Here, we describe the chemical methodology to access linkage specific non-hydrolyzable Ub-NEDD8-based chains endowed with an affinity handle in all possible combinations of K48 hybrid chain dimers between Ub and NEDD8.
