    Ubiquitin Antibody detects ubiquitin, polyubiquitin and ubiquitinated proteins. This antibody may cross-react with recombinant NEDD8.

    Species Reactivity:

    All Species Expected

    The antigen sequence used to produce this antibody shares 100% sequence homology with the species listed here, but reactivity has not been tested or confirmed to work by CST. Use of this product with these species is not covered under our Product Performance Guarantee.

    Species predicted to react based on 100% sequence homology:

    D. melanogaster, Xenopus, Zebrafish, Bovine, Pig, Horse

    Source / Purification

    Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to the amino terminus of the human ubiquitin protein. Antibodies are purified by protein A and peptide affinity chromatography.

    Background

    Ubiquitin is a conserved polypeptide unit that plays an important role in the ubiquitin-proteasome pathway. Ubiquitin can be covalently linked to many cellular proteins by the ubiquitination process, which targets proteins for degradation by the 26S proteasome. Three components are involved in the target protein-ubiquitin conjugation process. Ubiquitin is first activated by forming a thiolester complex with the activation component E1; the activated ubiquitin is subsequently transferred to the ubiquitin-carrier protein E2, then from E2 to ubiquitin ligase E3 for final delivery to the epsilon-NH2 of the target protein lysine residue (1-3). The ubiquitin-proteasome pathway has been implicated in a wide range of normal biological processes and in disease-related abnormalities. Several proteins such as IκB, p53, cdc25A, and Bcl-2 have been shown to be targets for the ubiquitin-proteasome process as part of regulation of cell cycle progression, differentiation, cell stress response, and apoptosis (4-7).
