Replacement Information
Description
OverviewRecombinant, human ErbB2 fused at the N-terminus to a GST-thrombin cleavage site sequence and expressed in S. frugiperda insect cells using a baculovirus expression system. ErbB2 is a component of a neuregulin-receptor complex that regulates neuromuscular synapse formation. It plays an important role in muscle spindle development. Overexpression of ErbB2 is reported in ~30% of all breast cancer cases. Amino acid sequence human ERB2 679-1255.

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(Glu,Tyr)4:1, 250 ng/50 µl final concentration ErbB2, GST-Fusion, Human, Recombinant, S. frugiperda, diluted in 1X 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 ErbB2. 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.
