Source:Recombinant corresponding to aa2-end of human UbcH5a with N-terminal HIS tag expressed in E. coli (NM_003338).
Specific Activity:50ul reaction mix (4mM ATP, 5mM MgCl2, 1mM DTT, UBE1 (0.5ug), UbcH5a or other E2, Biotin-Ubiquitin (0.5ug) and Smurf2 (2) in 50mM Tris pH 7.4 for 30 min at 37°C, then add to streptavidin coated plates for 30 min at 37°C. Incubate with anti-Smurf2, then Europium-labeled secondary antibody, and detect by time resolved fluorescence (lambda-ex=330nm, lambda-em=620nm).
Applications:Suitable for use in the study of enzyme kinetics, screening inhibitors and selectivity profiling. Other applications not tested.
Recommended Dilution:Optimal dilutions to be determined by the researcher.
Storage and Stability:Aliquot to avoid repeated freezing and thawing. Store at -70°C. Aliquots are stable for at least 6 months at -70°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
