Application Notes
This Ubiquitin Antibody (Ubi-1) is useful for Western blot, ELISA, Immunocytochemistry/Immunofluorescence, and Immunohistochemistry on both paraffin-embedded and frozen sections. In Western blot a band can be seen at 8.5 kDa. This antibody is excellent for the detection of ubiquitinated inclusions seen in human neurodegenerative diseases such as the neurofibrillary tangles of Alzheimer's disease. The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

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.

CommentsWorks well for WB on total cell lysates (boiling the membrane (nitrocellulose) can increase signal drastically if it is low, e.g. when blotting on primary cells/tissues), and it works really well for WB on Ubiquitin pulldowns, e.g. after a TUBE (tandem ubiquitin-binding entity) pulldown.

FAQs for Ubiquitin Antibody (NB300-130). (Showing 1 - 1 of 1 FAQs).

  1. Regarding the WB image on datasheet of NCX1 antibody (6H2) (NB300-127), can you confirm if lane 2 is a rabbit heart sample? In addition, can you provide the dilution fold and loading mount used to obtain this image? Lastly, would you happen to know if t
    • A protein stabilizer has not been added to the antibody NB300-130. However, note that this antibody is supplied as ascites fluid, not as a purified antibody. If you are not familiar with this format, the following descriptions will be useful: Ascites fluid is a complex solution containing multiple proteins and background antibodies as well as the antibody of interest. Ascites contains the antibody produced by the hybridoma cells as well as many other proteins, including background antibodies produced by the mice and albumin. Antibody concentrations in ascites are typically high, but an accurate concentration of the target antibody cannot be readily determined. Therefore, unfortunately you cannot determine the concentration of the ubiquitin antibody within NB300-130 as sold. This is why this product's pack sizes are volumes rather than masses, and why we state on our datasheet: 'This product is unpurified. The exact concentration of antibody is not quantifiable.' All I can suggest is that you carry out antigen affinity chromatography of the antibody, and then determine its concentration.
