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

Concentration: 1 mg/ml  

Molecular Weight: ~30 kDa  

Protein Sequence: Accession number: NP_004350. 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 His-UBE2R1 was validated by loading E1 UBE1 activated ubiquitin onto the active cysteine of the His-UBE2R1 E2 enzyme via a transthiolation reaction. Incubation of the UBE1 and His-UBE2R1 enzymes in the presence of ubiquitin and ATP at 30oC was compared at two time points, T0 and T10 minutes. The sensitivity of this ubiquitin/His-UBE2R1 thioester bond to the reducing agent DTT was confirmed.
