| Inhibition Assay |
Description: | Inhibition of Rho kinase 2 and Rho kinase 1 activity was determined using the IMAP™ Screening Express Kit (Molecular Devices product number #8073). Rho kinase 2 enzyme (Upstate/Chemicon #14-451), Rho kinase 1 (Upstate/Chemicon #14-601) and Flourescein tagged substrate peptide F1-AKRRRLSSLRA (Molecular Devices product number R7184) was pre-incubated with a test compound for 5 minutes in buffer containing 10 mM Tris-HCl pH 7.2, 10 mM MgCl2, and 0.1% BSA. Following the pre-incubation, 10 μM ATP was added to initiate the reaction. After 60 minutes at room temperature, Molecular Devices IMAP™ binding solution was added to bind phosphorylated substrate. After 30 minutes of incubation in the presence of the IMAP™ beads, the fluorescence polarization was read and the ratio was reported as mP. |
