Anti-Diglycyllysine Rabbit pAb

Anti-Diglycyl-Lysine Rabbit pAb selectively captures peptides/proteins bearing K-?-G-G residues, which are remnants of ubiquitin left in protein substrates after trypsin digestion, or SUMO remnants generated by £-lytic protease WaLP digestion. This pan antibody recognizes diglycyl-lysine independent of its surrounding sequences and has been well utilized to affinity purify peptides for global proteomic screening of ubiquitination and SUMOylation.
