Polyubiquitin chains linked through the Lys48 residue of ubiquitin are most commonly associated with proteins targeted for proteosomal degradation. In contrast, polyubiquitin chains linked through the Lys63 residue of ubiquitin (Ub) are associated with nonproteolytic functions such as signal transduction. Lys63-linked polyUb chains connect components of NFkappaB signaling in a highly regulated manner, and genetic evidence indicates the involvement of Lys63-linked Ub chains in stress response and DNA repair. Research in yeast has suggested Lys63-linked Ub chains stimulate endocytosis.
Applications:
Suitable for use in Western Blot, Immunoprecipitation, Immunohistochemistry, Immunocytochemistry, Inhibition and Flow Cytometry. Other applications not tested.
Catalog #U1000-06Q
Recommended DilutionsWestern Blot: 1:1000
Immunoprecipitation: Precipitated ubiquitin-containing proteins from HeLa cell lysates.
Immunohistochemistry: Ubiquitin (Lsy63 specific) staining of colorectal cancer tissue sections is restricted to tumor cells.
Immunocytochemistry: Ubiquitin (Lsy63 specific) staining of colorectal cancer tissue sections is restricted to tumor cells. Positive staining was also detected in mouse, rat and rabbit brain sections.
Inhibition: Preincubation of U1000-06Q with K63- multiubiquitin chains inhibited binding to HeLa cell lysate in Western Blots.
Optimal dilutions to be determined by the researcher.
Positive Control Lys63 polyubiquitin chains
Recommended Secondary AntibodiesI1904-46E: IgG, H&L (HRP) DkxRb
I1904-46K: IgG, H&L X-Absorbed (HRP) DkxRb
