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).


Recombinant Arabidopsis thaliana ubq11, with N-terminal His-tag; UniProt:P0CH33, TAIR: AT4G05050

Host Rabbit
Clonality Polyclonal
Purity Serum
Format Lyophilized
Quantity 50 µl
Reconstitution For reconstitution add 50 ĩl of sterile water
Storage Store lyophilized/reconstituted at -20°C; once reconstituted make aliquots to avoid repeated freeze-thaw cycles. Please, remember to spin tubes briefly prior to opening them to avoid any losses that might occur from lyophilized material adhering to the cap or sides of the tubes.

application example


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 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.
