{{/_source.additionalInfo}}Anti-UBQ11 | Ubiquitin (affinity purified)
(Cat#: AS08 307A)
Description
- Immunogen: Recombinant Arabidopsis thaliana ubiquitin, ubq11, with N-terminal His-tag; TAIR: At4g05050
- Host: Rabbit
- Clonality: Polyclonal
- Purity: Immunogen affinity purified serum in PBS pH 7.4.
- Format: Lyophilized
- Quantity: 50µg
- Reconstitution: For reconstitution add 20 µl of sterile water to each tube before use.
- Storage: Store lyophilized/reconstituted at -20°C; once reconstituted make aliquots to avoid repeated freeze-thaw cycles. Please remember to spin the tubes briefly prior to opening them to avoid any losses that might occur from material adhering to the cap or sides of the tube.

- Not reactive in: Algae
- 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).

- Antibody can be used to check qubiquitination status in the whole plant extracts.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.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.
