This application describes pharmaceutical compositions, kits, and methods for inhibiting cell proliferative disorders, especially those disorders characterized by overactivity andor inappropriate activity of a receptor tyrosine kinase, including Her2 related cancers, and methods for imaging an Her-2 expressing tumor. The inner shape of a flow-down port forming part corresponds to the inner shape of a cylindrical space forming part. When the user presses the second extended portion, the curved portion of the kinetic energy transferring element can protrude to touch the electric switch. Connecting the gates to appropriate voltage sources such as the SCR anode input voltage and the SCR cathode voltage, typically ground, reduces normal operation leakage of the ESD protection device.
