product information

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).

Source of positive control, ubiquitin protein: full length recombinant Arabidopsis thaliana ubiquitin, ubq11, with N-terminal 1XHis-3XHA-tag; locus accession: At4g05050

application example


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 ECL.

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.
