High purity inhibitor of deubiquitinylating enzymes (DUBs). Synthetically modified recombinant ubiquitin. The modification of the C-terminal glycine carboxyl into an aldehyde results in a potent, highly specific inhibitor of all ubiquitin deconjugating enzymes, including ubiquitin C-terminal hydrolases (UCHs), ubiquitin-specific proteases (USPs) and deubiquitinylating enzymes (DUBs). Alternative name: Ub-H. MW: 8.5kDa. Purity: ≥95% (HPLC). Sequence Recombinant Ubiquitin (corresponding to UniProt sequence P62988). The C-terminal glycine carboxyl is synthetically modified to an aldehyde. Formulation: Liquid. In aqueous solution containing 0.15M HCl. Source: Produced in E.coli. UniProt: P0CG47 (UBB), P0CG48 (UBC), P62979 (RPS27A), P62987 (UBA52). Handling: Do not neutralise until immediateley prior to use. Do not lyophilize. Avoid presence of amino-containing compounds. Soluble and stable in aqueous solution at pH <7.0. Long Term Storage: +4°C
