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 ubiquitin, ubq11, with N-terminal His-tag; TAIR:  At4g05050

Host Rabbit
Clonality Polyclonal
Purity Affinity purified serum
Format Lyophilized
Quantity 50 ĩg
Reconstitution For reconstitution add 50 ĩl of sterile water

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.

Tested applications Western blot (WB)

application example

 western blot using affinity purified anti plant ubiquitin antibody


10 μl of a total protein from Arabidopsis thaliana wt (20 μg of total protein) and Nicotiana benthamiana, was separated on 8% polyacralymide gel and blotted on PVDF membrane. Filters were blocked in 5% milk for 1h, incubated with 1: 5 000 anti-ubiquitin antibody (3h), followed by incubation with 1: 10 000 secondary anti-rabbit antibodies (1h) coupled with HRP and visualization (1 minute 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.
