AS08 307 western blot ubiquitin.jpg


5 μg of recombinant protein from Phytophora sp. (1), human (2), Arabidopsis thaliana His-tagged ubiquitin (3), Arabidopsis thaliana His-tagged SUMO protein (4), was separated on 15% PAA gel and blotted on PVDF membrane. Filters were blocked in 5% milk for 1h, incubated with 1: 10 000 anti-ubiquitin antibody (1h), followed by incubation with 1: 15 000 secondary anti-rabbit antibodies(1h) coupled with HRP and visualization (10 seconds exposure) with standard chemiluminescent detection reagent.

Technical note: It is very difficult to detect ubiquitin monomers in total cell extracts due to a great abundance of poly and multi-ubiquitinated proteins. Recommended is size separation of protein extracts before gel electrophoresis focused on good resolution of region between 6-10 kDa. 

Additional information

Additional information Ubiquitin mutant is lethal, therefore could not be used in validation of this antibody.
Suggested extraction buffer: 100 mM Tris-HCl, pH 8.0, 0.1% [w/v] SDS, 0.5% [w/v] sodium deoxycholate, 1% [v/v] glycerol, 50 mM sodium metabisulfite, 20 mM N-ethylmaleimide (NEM) and protease inhibitor cocktail (Roche) (Orosa et al. 2018). This buffer will help to stabilize the conjugates and will help to detect any increase or decrease in conjugate accumulation using the antibodies.

Ubiquitin is a highly conserved regulatory protein expressed in all eukaryotic tissues. Originally this protein was called: Ubiquitous Immunopoietic Polypeptide. Its function is labeling of proteins for degradation through ubiquitin proteasome system (UPS).
