摘要： The objective of the present invention is to provide a method for effectively and easily reducing an amount of a specific impurity in a liquid. The method for reducing an amount of a nucleic acid in a liquid according to the present invention is characterized in comprising the steps of contacting the liquid with a water-insoluble magnesium compound to adsorb at least a part of the nucleic acid on the water-insoluble magnesium compound. Also, the objective of the present invention is to provide an adsorbing filter useful for purifying a useful substance, such as an antibody and an antibody-like molecule, used as a purification material for effectively removing an impurity with easily maintaining the yield of the target substance due to excellent adsorption ability to a nucleic acid and low adsorption ability to an antibody, an antibody-like molecule or the like. The adsorbing filter is characterized in comprising the layer comprising a water-insoluble magnesium compound.

摘要： A fermenter can have at least one hollow fluid conduit disposed at least partially within a vessel. An external circumference of the hollow fluid conduit and an interior circumference of the vessel can define a downward flow path through which a multi-phase mixture including a liquid media and compressed gas substrate bubbles flows. An interior circumference of the hollow fluid conduit can defined an upward flow path which is in fluid communication with the downward flow path. The multi-phase liquid can flow through the upward flow path and exit the fermenter. Cooling may be provided in the hollow fluid conduit or the vessel. One or more backpressor generators can be used to maintain a backpressure on the fermenter. One or more fluid movers can be used to variously create an induced and/or forced flow in the downward and upward flow paths.

摘要： Devices and methods are provided for electrically lysing cells and releasing macromolecules from the cells. A microfluidic device is provided that includes a planar channel having a thickness on a submillimeter scale, and including electrodes on its upper and lower inner surfaces. After filling the channel with a liquid, such that the channel contains cells within the liquid, a series of voltage pulses of alternating polarity are applied between the channel electrodes, where the amplitude of the voltage pulses and a pulsewidth of the voltage pulses are effective for causing irreversible electroporation of the cells. The channel is configured to possess thermal properties such that the application of the voltage produces a rapid temperature rise as a result of Joule heating for releasing the macromolecules from the electroplated cells. The channel may also include an internal filter for capturing and concentrating the cells prior to electrical processing.

摘要： Systems, devices, and methods for removing areas of tissue are described. A programmable laser may remove precise areas of tissue while the tissue remains substantially frozen. The laser is programmed in part by analyzing a reference image of a representative tissue section. A software program may receive digital images of test slices. Areas of interest in the image may be selected by a user. The software program can then create and send cut instructions to the programmable laser. The laser may be configured to make perforated cuts to remove the area of interest without melting the removed section.
