Me-Ub

Lyophilized solid. AVOID FREEZE/THAW CYCLES. Recombinant, human methylated ubiquitin. A derivative of ubiquitin in which lysine residues are reductively methylated. Methylated ubiquitin can ligate to protein substrates, but does not form polyubiquitin chains. Protein breakdown rates obtained with methylated ubiquitin are slower than those obtained with unmethylated ubiquitin. Useful for reducing the polyubiquitin chain length and for determining rates of ubiquitin conjugation. Purity: ≥95% by SDS-PAGE.
