6 results about "Selective isolation" patented technology

Described herein are devices, systems, and methods for selectively isolating a molecule. The method includes forming a first complex having a first molecule and a particle, the first particle being disposed on a first working electrode, the first working electrode electrically coupled to a first counter electrode via a first solution; modulating an energy of the first working electrode relative to the first counter electrode to release the first complex from the first working electrode into the first solution.

The description relates to hinged devices, such as hinged computing devices that include a pop-up function. One example can include a first portion and a second portion that are rotatably secured through a range of rotation from an open orientation to a closed orientation. This example can also include a selective isolation assembly configured to convert rotational torque associated with rotating the first and second portions toward the closed orientation to a compressive force that compresses a spring. The selective isolation assembly is configured to disconnect the first and second portions and the compressed spring as the first and second portions approach the closed orientation.

The application belongs to the technical field of microbial culture, and discloses a selective separation culture medium for gram-negative bacteria and application of the culture medium in rapid separation, purification and identification of gram-negative bacteria in samples such as aquatic products, food, water and soil. The selective separation culture medium takes a perylene quinone photosensitive compound as a key active component.

A method for selectively isolating microbial cell analytes (e.g., nucleic acids) from a sample containing or suspected of containing mammalian cells is disclosed. The selective isolation method comprises selective lysis of mammalian cells, filtration of the lysate obtained by passing it through a filter that retains intact microbial cells, and subsequent release of the retained microbial cells from the filter. The microbial cells are then collected from the filter using backflow elution or aspiration, and the collected microbial cells are lysed to release the analytes from the intact cells. The isolated analytes can be analyzed using appropriate assays depending on the type of analyte molecule.

The utility model relates to the field of bee breeding, in particular to a disease-resistant bee breeding isolation box which comprises a beehive body. The beehive comprises a beehive body and further comprises a mounting base, a mounting groove, reset rotating shafts, waterproof cloth, a mounting plate, a waterproof motor, a transmission shaft, a pull rope, a hook and a connecting ring, the mounting base is arranged on the surface of the front side of the beehive body, the mounting groove is formed in the front position of the upper surface of the mounting base, and the left side and the right side of the inner surface of the mounting groove are rotationally connected with the reset rotating shafts; the outer surface of the reset rotating shaft is connected with one end of waterproof cloth; by arranging the waterproof motor, the output end of the waterproof motor can drive the transmission shaft to rotate during operation, the transmission shaft can wind the pull rope during rotation, and the hook at the end of the pull rope is matched with the connecting ring to pull the waterproof cloth to be laid on the upper surface of the beehive body, so that the waterproof cloth is protected; at the moment, the reset rotating shaft rotates, so that the waterproof cloth is wound again.

The invention relates to the technical field of microbiological detection, and particularly discloses a culture medium for selectively separating and culturing Burkholderia cepacia, which comprises the following components: 8-12 g / L of tryptone, 8-12 g / L of sucrose, 1-2 g / L of yeast extract, 1-2 g / L of monopotassium phosphate, 5-10 g / L of sodium pyruvate, 4-7 g / L of sodium chloride, 15-23 mg / L of phenol red, 10-18 g / L of agar, 0.8-1.3 mg / L of crystal violet, 0.5-5 g / L of selective inhibitor, and the balance of water. 10-30 g / L of a specific accelerant and the balance of water; the selective inhibitor is selected from one or more of sodium deoxycholate, sodium taurocholate, sodium glycocholate and propyl gallate; the specific accelerant is lactose, cane sugar and vanillic acid; and the culture medium does not contain any antibiotic component. The culture medium disclosed by the invention is free of antibiotic components, good in selectivity and high in growth promoting ability, and has a very good market application prospect.
