Anti-Ubiquitin Antibody, Lys48-Specific, clone Apu2, rabbit monoclonal

DI-UBIQUITIN PROTEIN AVAILABLE!
Di-Ubiquitin (Lys48-linked) Recombinant Protein (17-10408)

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 NFκB 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.

Epitope: Lys48 ubiquitination site

Immunogen used was human di-ubiquitin linked at Lys48.

Immunohistochemistry:
Ubiquitin (Lys 48-specific) staining of rat brain sections (left figure) or human breast carcinoma (right figure). Staining pattern detects axons of neurons in brain tissue but not surrounding glial cells, and breast tumor cell cytoplasm is strongly detected without nuclear involvement.

Immunocytochemistry:
Confocal IF analysis of NIH/3T3, HeLa, and A431 cells using anti-Ubiquitin (Lys48 specific) (Red). Actin filaments were labeled with AlexaFluor 488-Phalloidin (Green). Nuclear material is stained with DAPI (Blue).

Flow cytometry:
Flow cytometry analysis of Jurkat cells using Anti-ubiquitin Lys48-specific (#05-1307) (blue) and rabbit IgG control (red).

Immunoprecipitation:
Rabbit monoclonal anti-ubiquitin (Lys-48-specific), clone Apu2, precipitated ubiquitin-containing proteins from HeLa cell lysates.

Inhibition Assay:
Preincubation of anti-ubiquitin, Lys48-specific, with K48-multiubiquitin chains inhibited binding to HeLa cell lysate in Western blots.

Anti-Ubiquitin Antibody, Lys48-Specific, clone Apu2 is a high quality Rabbit Monoclonal Antibody for the detection of Ubiquitin & has been validated in FC, ICC, IP, IHC, WB, PIA.
