Storage/Stability

>6 months at -80°C.

Assay Conditions

50 µl reaction mix (4 mM ATP, 5 mM MgCl₂, 1 mM DTT, UBE1 as an E1 (0.5 µg), UbcH7, Biotin-Ubiquitin (0.5 µg) and Smurf2 as an E3(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).

Instructions for Use

Thaw on ice and gently mix prior to use. DO NOT VORTEX. Perform a quick spin before opening. Aliquot into small volumes and flash freeze for long term storage. Avoid multiple freeze/thaw cycles.

Applications

Useful in conjunction with E1 and E3 for the study of enzyme kinetics, screening inhibitors, and selectivity profiling.

Shipping Temperature

-80°C

Warnings

Avoid freeze/thaw cycles
