Overview

This product has been discontinued.





Recombinant, human IGF-1R 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. IGF-1R belong to the tyrosine kinase receptor family that mediates cell survival and growth in response to its ligands, IGF-1 and IGF-2. It is also involved in the proliferation of transformed cells.

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, 1 µg/50 µl final concentration IGF1-R, GST-Fusion, Human, Recombinant, S. frugiperda, diluted in 1X Kinase Dilution Buffer to desired concentration (we use 40 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 IGF1-R. 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.
