UbcH5a Human, recombinant, N-terminal His tag Catalog #: 80315
Size: 100 µg
Description: Human UbcH5a (GenBank Accession No. NM_003338), amino-acids
2-end, with N-terminal HIS tag, MW=17 kDa, expressed in an E. coli expression system. Activity Assay: 50 μl reaction mix (4 mM ATP, 5 mM MgCl2, 1 mM DTT, UBE1 (0.5 μg), UbcH5a or other E2, Biotin- Ubiquitin (0.5 μg) and Smurf2 (2 μg) in 50 mM 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 (λex=330 nm, λem=620 nm).
Application: Useful for the study of enzyme kinetics, screening inhibitors, and
selectivity profiling. Formulated in: 25 mM Tris-HCl, pH 8.0, 100 mM NaCl, 0.05% Tween-20, 20% glycerol, and 3 mM DTT. Stability: >6 months at –80°C References: 1. Markson G. et al., Genome Res. (2009) 19, 1905-1911. 2. Nuber U. and Scheffner M., J. Biol. Chem. 274 (11), 7576-7582 (1999).
