We have developed a novel analyte injection method for the SensíQ Pioneer surface plasmon resonance-based biosensor referred to as " FastStep." By merging buffer and sample streams immediately prior to the reaction flow cells, the instrument is capable of automatically generating a two- or threefold dilution series (of seven or five concentrations, respectively) from a single analyte sample. Using sucrose injections, we demonstrate that the production of each concentration within the step gradient is highly reproducible. For kinetic studies, we developed analysis software that utilizes the sucrose responses to automatically define the concentration of analyte at any point during the association phase. To validate this new approach, we compared the results of standard and FastStep injections for ADP binding to a target kinase and a panel of compounds binding to carbonic anhydrase II. Finally, we illustrate how FastStep can be used in a primary screening mode to obtain a full concentration series of each compound in a fragment library. © 2010 Elsevier Inc. Source

Patent
ICx Technologies | Date: 2010-06-23

A method for linearizing a radiation detector is provided, the method including measuring a pulse height spectrum of a predetermined radiation source, identifying at least one spectrum template for the predetermined radiation source, and determining a linearization function by comparing the measured pulse height spectrum with the at least one identified spectrum template. The at least one spectrum template is a predefined synthesized energy spectrum for the predetermined radiation source and for the corresponding radiation detector. Further, a detector for measuring one or more types of radiation is provided, the detector being adapted for transforming the measured pulse height spectrum in an energy-calibrated spectrum, the transformation including a linearization step, where a linearization function used with the linearization step is determined according to the inventive method.
