Species Reactivity: Human  

Source: E. coli expression  

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

Concentration: 1 mg/ml  

Molecular Weight: ~73 kDa  

Protein Sequence: Accession number: NP_060052. For full protein sequence information download the Certificate of Analysis pdf.  

Quality Control Protein Identification: Confirmed by mass spectrometry.  

Quality Control Activity:  E2-Ubiquitin Thioester Loading Assay: The activity of GST-UBE2Q1 was validated by loading E1 UBE1 activated ubiquitin onto the active cysteine of the GST-UBE2Q1 E2 enzyme via a transthiolation reaction. Incubation of the UBE1 and GST-UBE2Q1 enzymes in the presence of ubiquitin and ATP at 30 °C was compared at two time points, T0 and T10 minutes. Sensitivity of the ubiquitin/GST-UBE2Q1 thioester bond to the reducing agent DTT was confirmed.
