    摘要: The invention relates to biological microbeads, and in certain embodiments, to the use thereof in flow-cytometric applications. Biological microbeads are fixed cells that may be surface-modified with proteins or other molecules that have specific binding properties. These surface-bound proteins may bind to target compounds bearing fluorescent labels that facilitate detection by flow cytometry. Provided are compositions and methods for the use of biological microbeads as an inexpensive alternative to synthetic microbeads for in an extensive number of flow-cytometric applications, including quantitative PCR, detection of nucleases, detection of proteases, and immunoassays.

    摘要: A process for the hygienic extraction and separate collection of animal blood fit and unfit for consumption, comprises stunning the animals prior to stabbing and providing the animals with serial numbers suitable for identification of the carcass and the blood to be extracted. The spot of stabbing on the throat of the animals is disinfected and the animals are cyclically stepped into a stabbing position. The animal is stabbed in the stabbing position with a disinfected stabbing tool which is exchanged for each animal and is provided with a closed outlet a hose-fitted hollow knife. The hygenic blood is extracted through the stabbing tool into one of a plurality of rotating blood collecting tanks arranged on a turntable and moved into an extracting position. An anticoagulant is added to the blood by gravity feed and after filling, the tanks are advanced toward into a first draining position for blood fit for consumption. If all the numbered carcasses pertinent to the blood in the tank in the first drawing position are held impeccable from the point of view of animal healthy examination, a control body effects the draining the blood from the collecting tank into a system for blood fit for consumption. If not impeccable, the tank is advanced with the blood in it forward to a second draining position and drained into a system for blood unfit for consumption. The drained tanks are washed and disinfected and advanced into the extracting position.

    摘要: The invention relates to an apparatus for and a method of spreading gaseous, liquid and powdered materials, that are applicable to pressing out creamy or foamy materials, too. According to the method a material to be spread is placed in a tank into the pressure vessel, overpressure is developed in the pressure vessel for spreading, whereby the tank moves towards the spreading nozzle and the spreading nozzle is communicated with the interior of the tank. The apparatus comprises a pressure vessel with its interior space divided into two sections, one of them contains the fuel tank ensuring the overpressure, the other one contains the material tank sealing airtightly the first section. The invention provides reliable spreading, not polluting the environment, the pressure vessel of the apparatus is not to be thrown away, and the tanks inside the vessel are replaceable.
