一般描述

Human WWP1 (GenBank Accession No. NM_007013), amino acids 2-end, with N-terminal DDDDK tag (FLAG), MW = 106 kDa, expressed in a Baculovirus infected Sf9 cell expression system.

应用

Useful in conjunction with E1 and E2 for the study of enzyme kinetics, screening inhibitors, and selectivity profiling.

单位定义

One unit is defined as the amount of enzyme required to transfer 1 pmol of ubiquitin to substrate/min at 37°C.

外形

Formulated in 25 mM Tris-HCl, pH 8.0, 100 mM NaCl, 0.05% Tween-20, 100 μg/ml FLAG peptide, 20% glycerol and 3 mM DTT.

制备说明

Thaw on ice. Upon first thaw, briefly spin tube containing enzyme to recover full content of the tube. Aliquot enzyme into single use aliquots. Store remaining undiluted enzyme in aliquots at -70°C. Note: Enzyme is very sensitive to freeze/thaw cycles.
