Description
OverviewRecombinant, human Wee1 fused at the N-terminus to a GST-His6-thrombin cleavage site sequence and expressed in S. frugiperda insect cells using a baculovirus expression system. Wee1 is a tyrosine kinase that causes inhibitory phosporylation of Cdk1 and Cdk2 and acts as a mitotic inhibitor. Protects the nucleus from cytoplasmically activated cyclin B1-complexed CDC2 prior to the onset of mitosis.

Recommended reaction conditions
96-Well Membrane Binding Kinase Activity Assay Protocol:
Materials Required • Standard Kinase Assay Buffer: 125 mM HEPES-NaOH, 7.5 mM MgCl2, 7.5 mM MnCl2, 7.5 µM sodium -orthovanadate, 2.5 mM DTT, pH 7.5 • 10X Kinase Dilution Buffer: 500 mM HEPES-NaOH, 2.5 mg/ml PEG20.000, 10 mM DTT, pH 7.5 • Substrate: Poly(Ala,Glu,Lys,Tyr)6:2:5:1, 1 µg/50 µl final concentration • WEE1, GST-Fusion, Human, Recombinant, S. frugiperda, diluted in 10X Kinase Dilution Buffer to desired concentration (we use 200 ng in a 50 µl reaction) • 33P-γ-ATP • ATP Mix: 1 µM ATP in H2O with 1 x 106 cpm/5 µl • 96-well V-bottom MTP (polypropylene) plates (Nunc Cat. No. 442587) • 96-well Multiscreen Vacuum Manifold (Millipore Cat. No. MAVM096OR) • 96-well Multiscreen Filterplates, phosphocellulose membrane (Millipore Cat. No. MSPH N6B50) and glass fiber (Millipore Cat. No. MSFC N6B50) • 2% H3PO4 • 0.9% NaCl
Activity Assay Protocol 1. In a polypropylene V-bottom plate add 20 µl Kinase Assay Buffer. 2. If desired, add 5 µl test substance (e.g., inhibitor, activator, etc.; in 10% DMSO). 3. Add 10 µl Substrate (diluted in H2O). 4. Add 10 µl diluted WEE1. 5. Add 5 µl ATP Mix. 6. Mix on a shaker and incubate at 30°C for 80 min. 7. Stop the reaction with 50 µl H3PO4. 8. Prewet the filter plate with 200 µl H2O. 9. Filter the reaction mix by applying vacuum. 10. Wash 3 times with 200 µl 0.9% NaCl. 11. Add 200 µl scintillation fluid to each well and count on a scintillation counter.
