Notes
50 ul reaction mix (4 mM ATP, 5 mM MgCl2, 1 mM DTT, UBE1 (0.5 ug), UEV1A or other E2, Biotin-Ubiquitin (0.5 ug) and Smurf2 (2 ug) in 50 mM Tris, pH 7.4) for 30 min at 37°C. Add to Streptavidin-coated plates for 30 min at 37°C. Incubate with anti-Smurf2, then HRP-labeled secondary antibody, and chemiluminescent detection.
