Abstract: A method of and system for intervening between a wireless communication device and a base station. A receiver is used to scan for transmissions from multiple surrounding base stations. The absolute field strength of all received transmission is measured and the information transmitted by the base stations is recorded. Then the transmission power level of a transmitter is set to have an absolute field strength greater than the highest measured absolute field strength detected from a corresponding base station. When an interface signal from a wireless communication device is received, the corresponding information is transmitted to the wireless communication device to thereafter control the wireless communication device by establishing a communication channel between the wireless communication device and the receiver and transmitter instead of between the wireless communication device and a surrounding base station to prevent use of the wireless communication device proximate the receiver and transmitter.

Abstract: The disclosure provides compositions and methods for heavy atom labeling of a target protein using a clonable tag. The clonable tag comprises a metal binding protein, or fragment thereof, such as metallothionein, which may be fused to a target protein of interest. The tag permits the target protein to be labeled with a heavy atom, such as gold, silver, or mercury, and thus permits visualization of the target protein by electron microscopy. Also provided are methods for purification of a target protein using metallothionein, or a fragment thereof, as an affinity tag. The metallothionein fusion may be purified on immobilized metal affinity chromatography (IMAC) column charged with a metal such as cadmium.
