Quantity: 
5 mg
Data Sheet: 

Cell fraction containing the full HeLa cell compliment of E1, E2s, E3s, 20S and 26S proteasomes, isopeptidases, and PA28. Useful in assays to demonstrate ubiquitin conjugation and degradation.

Product Information

Stock: 
X mg/ml in 50 mM HEPES pH 7.6, 20mM NaCl, 0.5 mM DTT.Actual concentration varies with lot number. 

Use & Storage

Use: 

Ideal for demonstrating ubiquitin proteasome degradation/ conjugation of radiolabeled or immuno-detectable substrates. Typical assay concentration for extract is 0.5-4 mg/ml. Isopeptidase inhibitor (U-201) and a proteasome inhibitor are highly recommended for the efficient accumulation of ubiquitinprotein conjugates.

Storage: 
Store at -80°C. For best results, aliquot and freeze after first set of experiments to avoid multiple freeze/thaw cycles.
