  • Patent number: 10900938
    Abstract: Valves, pumps, detectors, sample loops, fraction collectors and the like are individually incorporated into modules that are mountable at individual mounting sites on a base unit which also supports one or more chromatography columns. Each module includes fluid connections to other modules and a microcontroller joining the module to a computed and monitor through an electronic connector at each mounting site. The fluid connections between the modules and the column(s) are removed from the electronic connections and accessible to the user. A software platform may recognize the modules and their locations, coordinate fluid connections between the modules, and provide a variety of control, monitoring, data generating and data processing functions to generate chromatographic data. The software platform may also provide graphical tools for designing chromatographic methods from a library of phases.

  • Patent number: 10852273
    Abstract: Methods, kits, and systems are provided for separating, immobilizing, and/or detecting analytes of one or more samples using dipsticks. A ‘dipstick’ is an object that can be embedded and subsequently removed from a separation medium, and to which analytes can be immobilized while the object is embedded in the separation medium. Examples of separation media include an electrophoresis gel of any format and a stationary phase for column chromatography. Embodiments of the present methods include applying a sample to a separation medium; separating analytes of the sample in the separation medium along a separation axis; immobilizing the analytes on a dipstick embedded in the separation medium; removing the dipstick from the separation medium; and detecting the analytes immobilized on the removed dipstick.

  • Patent number: 10846852
    Abstract: Systems and methods for producing blot images. A blot, for example a western blot, is imaged using an imaging system having a field of view and a magnification. Features of interest in the blot correspond to features in the digital image, and the sizes of the features in the digital image depend on the magnification of the imaging system. A structuring element is selected based on the sizes and shapes of the features in the digital image, and the image is morphologically eroded and dilated varying numbers of times. The eroded and dilated image is subtracted from the original blot image to remove background signal from the blot image, producing an output image. The number of erosions needed to completely erode the features of interest is determined automatically, for example by investigating the behavior of the kurtosis of the output image as a function of the number of erosions performed.
