Abstract: Methods for detecting and quantifying one or more microcystin compounds in a sample are described. The methods may include a preconcentration step, and generally utilize an LC-MS or LC-MS/MS analysis with an Orbitrap Fusion mass spectrometer or a QqQ mass spectrometer. The methods provide excellent recoveries and limits of quantification of microcystins.

Abstract: A method is provided for detecting a target molecule in a biological sample. One step of the method includes immobilizing the biological sample on a membrane. Next, the membrane-bound biological sample is contacted with at least one detection moiety. The membrane-bound biological sample is then separately mated with a substrate and the target molecule detected. At least one step of the method is performed under positive pressure or a vacuum.

Abstract: The present invention relates to an improved apparatus and method for assembly for a cylindrical split-flow thin separation channel that is capable of continuously separating particles of interest from a suspension flowing through the channel. The apparatus provides better precision in the separation process by providing better flow characteristics at the inlet, outlet, and in the zone of separation. Splitter surfaces are provided that match the calculated theoretical Inlet Splitter Surface (ISS) and Outlet Splitter Surface (OSS). A flow distributor diverts the inlet carrier flow into a stable, circumferentially uniform, laminar annular flow. The design enables manufacturing and assembly methods to ensure precise alignment of the components to further improve the flow profiles within the separation channel and to ensure repeatability device-to-device.

Abstract: A device for centrifugation and robotic manipulation of specimen samples, including incubating eggs, and uses thereof are provided. The device may advantageously be used for the incubation of avian, reptilian or any type of vertebrate eggs. The apparatus comprises a mechanism for holding samples individually, rotating them individually, rotating them on a centrifuge collectively, injecting them individually with a fixative or other chemical reagent, and maintaining them at controlled temperature, relative humidity and atmospheric composition. The device is applicable to experiments involving entities other than eggs, such as invertebrate specimens, plants, microorganisms and molecular systems.

Abstract: A hand-operated device comprising a handle having a rotatable shaft supported by the handle and one end projecting beyond one end of the handle and having means to support removably thereon a conventional hair curler. A spool is affixed to the shaft and has a flexible cord-like member coiled therearound, whereby when the outer end of said member is pulled, the shaft and curler thereon is rotated for purposes of winding hair upon the curler. For purposes of restoring the cord-like member to coiled condition, a circular friction member is mounted upon the shaft and is adapted to be rolled along a suitable surface in one direction to coil the cord-like member upon the spool to arrange the same in starting position.
