Species Reactivity: human  

Source: E.coli  

Formula: 50 mM HEPES pH 7.5, 150 mM sodium chloride, 2 mM dithiothreitol, 10% glycerol  

Concentration: 0.5 mg/ml  

Molecular Weight: ~111 kDa  

Protein Sequence: Accession number: NP_003354. For full protein sequence information download the Certificate of Analysis pdf.  

Quality Control Protein Identification: Confirmed by mass spectrometry.  

Quality Control Activity: Deubiquitylating Enzyme Assay: The activity of His-USP4 was validated by determining the increase in fluorescence measured as a  result of the enzyme catalysed cleavage of the fluorogenic substrate Ubiquitin-Rhodamine110-Glycine generating Ubiquitin and Rhodamine110-Glycine.  Incubation of the substrate in the presence or absence of His-USP4 was compared confirming the deubiquitylating activity of His-USP4.
