Background

Ubiquitin is a highly conserved protein of about 8.5 kDa molecular weight, which has a normal role in the targeting of proteins for proteolytic degradation. To perform this function, the protein to be degraded is first covalently attached to the C terminus of ubiquitin, and the ubiquitinated complex is then recognized by a complex of degradative enzymes. Interestingly, ubiquitin also becomes covalently bonded to many types of pathological inclusions, which appear to be resistant to normal degradation. Therefore, ubiquitin antibodies are very useful for studies of these inclusions. For example, the neurofibrillary tangles and paired helical filaments diagnostic of Alzheimer's disease, Lewy bodies seen in Parkinson's disease, and Pick bodies found in Pick's disease are all heavily ubiquitinated and can be readily visualized with ubiquitin antibodies.

GTX14372 WB Image

Western blot of Ubiquitin. Anti-Ubiquitin antibody (GTX14372), generated by immunization with Ubiquitin coupled to Rabbit IgG, was tested by western blot against total cell extract from yeast. Dilution of the antibody between 1:200 and 1:1,000 showed strong reactivity with Ubiquitinated proteins. In this blot the antibody was used at a 1:500 dilution incubated overnight at 4° C in 5% non-fat dry milk in TBST. Detection occurred using a 1:2,000 dilution of HRP-labeled Donkey anti-Rabbit IgG for 1 hour at room temperature.
