Abstract: The application provides methods for improving the detection accuracy of the binding of labeled nucleic acid probes, such as those used in PCR reactions. One such method comprises measuring the label intensity, e.g. fluorescence, at two different temperatures, a higher temperature and a lower temperature, and then calculating the ratio of the label intensity at the lower temperature over the label intensity at the higher temperature. Another method comprises measuring the label intensity at least two points in time post-PCR and calculating the slope of the label intensity as a function of time. Measuring the hybridization kinetics of the probe binding to the target nucleic acid allows an on-rate slope to be calculated which gives this method good specificity of detection.

Abstract: In a method to remove toner deposits on a surface of a cleaning element, electrically charged toner particles are transferred from a carrier surface to an intermediate carrier. On the cleaning element, untransferred, electrically charged toner particles as residual toner from the carrier surface are received. Electrically charged toner particles on the cleaning element are directed past an electrode arrangement arranged at a distance from the surface of the cleaning element.
