HA-Ubiquitin Aldehyde
Price: $130.00
HA-Ubiquitin Aldehyde
Price:
130
Quantity:
50 µg
Data Sheet:
Also known as: HA-Ubiquitin Aldehyde (HA-Ub-H)
Ubiquitin-aldehyde is a potent and specific inhibitor of most deubiquitinating enzymes (DUBs) such as ubiquitin C-terminal hydrolases (UCHs) and ubiquitin-specific proteases (USPs). It prevents the hydrolysis of poly-ubiquitin chains on substrate proteins in vitro and thus enhances poly-ubiquitin chain accumulation. This tagged version contains an N-terminal HA peptide sequence (YPYDVPDYA) derived from the influenza hemagglutinin protein. This epitope allows for the sensitive identification or purification of DUBs since it is specifically recognized by anti-HA antibodies and/or anti-HA-agarose.
Product Information
MW:
9.5 kDa
Purity:
> 95% by HPLC.
Solubility:
Resuspend in aqueous buffer to 2 mg/ml. Pellet dry compound prior to reconstitution.
Activity:
Ki = 2.5 nM vs. UCH-L3
Supplied:
This is a lyophilized powder Use & Storage
Use:
Add Recombinant Human HA-Ubiquitin Aldehyde to in vitro assays to inhibit Deubiquitinating enzymes. The HA-tag allows for detection and purification of Deubiquitinating enzymes activity. Reaction conditions will need to be optimized for each specific application. We recommend an initial Recombinant Human HA-Ubiquitin Aldehyde concentration of 2-5 μM.
Storage:
Store powder at -20°C. Store stock solution at -80°C. Avoid multiple freeze/thaw cycles.
