Abstract: An apparatus selectively generates a disturbance in a three-phase supply voltage provided to a load. The apparatus includes input connections for receiving a first phase voltage, a second phase voltage and a third phase voltage of the three-phase supply voltage. The apparatus includes a voltage disturbance generator for selectively adjusting the amplitudes of the first, second and third phase voltages according to a first test method, a second test method or a third test method. Output connections are provided for connecting to the load to provide the load the first, second and third phase voltages as altered according to the first, second or third test method. In the first test method, a phase-to-phase voltage disturbance is introduced between the first and second phase voltages by altering the amplitude of the first phase voltage against the second phase voltage.

Abstract: The present invention provides a fast and efficient means for identifying kinetically stable proteins. As used herein the term “kinetically stable protein” means a protein that is trapped in a specific conformation due to an unusually high unfolding barrier that results in very slow unfolding rates. The present inventors are the first to discover the existence of a correlation between kinetic stability and SDS-induced denaturation. Thus, the invention provides methods for identifying kinetically stable proteins comprising the step of testing the proteins for resistance to denaturation by SDS. In one embodiment, SDS-polyacrylamide gel electrophoresis (SDS-PAGE) is one simple method for quickly identifying and selecting kinetically stable proteins. In another embodiment a two-dimensional SDS-PAGE provides a high throughput method for quickly identifying kinetically stable proteins in a sample.
