Ubiquitin is a protein that plays a role in the targeting of proteins for proteolytic degradation. Ubiquitin becomes covalently bonded to many types of pathological inclusions seen in neurodegenerative diseases that appear to be resistant to normal degradation. The neurofibrillary tangles and paired helical filaments diagnostic of Alzheimer's disease, the Lewy bodies seen in Parkinson's disease, and Pick bodies found in Pick's disease are all heavily ubiquitinated and can all be readily visualized with this antibody.
Image: ABC-HRP staining with Ubiquitin monoclonal antibody (diluted 1:1,000) of Alzheimer’s disease cerebral cortex showing dystrophic neuritis, which contain ubiquitinated tau. The inclusions are detected by the Ubiquitin antibody. Normal cortex does not contain inclusions and would be white in color.
