  • Patent number: 9897520
    Abstract: Sample preparation device that allows for a complete bind, wash, elute, buffer-exchange and concentration process to be carried out without sample transfer between multiple devices. The device includes a reservoir, a column for holding chromatography media, a holder region for holding a filtration device, and an outlet. The filtration device plugs into the holder region of the centrifugal device, and the assembly can be placed in an optional holder. The assembly, with or without the optional holder, can be placed in a conventional centrifuge tube for centrifugation. The entire bind, wash, elute, buffer exchange and concentration steps can be carried out with the apparatus without any pipette transfers (and the associated sample losses. The sample preparation device also can be used for binding and washing steps, in which case the filtration device is not needed, and for buffer exchange and concentration steps, in which case the media is not needed.

  • Patent number: 8652422
    Abstract: The invention is directed to an apparatus useful in conducting detection of compounds on blotting membranes. The device is comprised of several layers including a porous support layer below the blotting membrane(s), a flow distributor above the blotting membrane(s) and optionally a well on the flow distributor to contain the liquid to the desired area and to allow for lower starting volumes of such liquid. Preferably, the flow distributor is a non-binding or low binding hydrophilic porous membrane such as a 0.22 micron membrane and the support layer is a grid or sintered porous material. The distributor and support are held together to form an envelope around the membrane(s). The use of a hinge, clips and other such devices is preferred in doing so.

  • Publication number: 20140011294
    Abstract: A rapid, efficient and convenient method to detect one or more biological entities on a blotting membrane is provided. The detection can relate to the position, nature or amount of the biological substance on one or more membranes. The invention method involves a pressure assisted regiment (such as vacuum or positive gas pressure) for the supply and removal of reagents and permits washing of the contaminants from substances embedded in the membrane to be detected using very low volumes of liquid. This method enables completion of the blocking, washing and antibody binding steps in about 30 minutes without comprising blot quality. In another aspect, the invention is directed to an apparatus useful in conducting the method of the invention.

  • Patent number: 7759055
    Abstract: Wash solution and method for purifying sequencing reaction product. The wash solution comprises an effective amount of guanidine in a low ionic solution to reduce or eliminate the presence of dye terminators in a sequencing reaction product. In its method aspects, the present invention comprises the addition of the wash solution to the sequencing reaction product prior to filtration, followed by filtration to reduce or eliminate unincorporated dye terminators. The purified sequencing products can then be resuspended and transferred to an appropriate substrate for sequencing or further preparation. Dye blobs formed from unincorporated dye terminators no longer interfere with the electropherograms generated upon electrophoresis of the sample.

  • Publication number: 20030036086
    Abstract: A system for holding a multiple welled plate during processing comprised of a multiple welled plate, typically containing 96, 384 or more individual wells, each having an open bottom closed by a membrane and a holder for such a plate. The holder is formed with a filter support portion that supports the lower surface of the filter during processing. The holder may optionally be thermally conductive or if not thermally conductive, may include an additional thermally conductive layer between the lowermost surface of the filter and the filter support portion to provide for thermal cycling applications.
