Abstract: One aspect of the present invention provides a method of manufacturing a multi-layer separator, which includes (a) extruding a first composition including a first polyolefin and a first pore forming agent to obtain a first sheet; (b) extruding a second composition including a second polyolefin and a second pore forming agent to obtain a second sheet; (c) stretching each of the first sheet and the second sheet in the machine direction (MD) to obtain a first precursor film and a second precursor film; (d) laminating the first precursor film and the second precursor film to obtain a stacked structure; and (e) stretching the stacked structure in the transverse direction (TD), and then removing the first pore forming agent and the second pore forming agent from the stacked structure.

Abstract: The present invention relates to an automatic real-time quantitative amplification system which can perform analysis of various biological samples, and more particularly to an automatic real-time quantitative amplification system in which a plurality of decks for respectively accommodating biological samples are put in a deck storing/transferring device, whereby it is possible to automatically analyze an amount or existence of a target substance containing a target nucleic acid in the biologic sample, such as a particular gene, a particular, a particular pathogenic bacterium and a particular protein, by amplifying the target nucleic acid purified by some processes of purification, purification after culture, or purification after reaction of the target substance contained in the biological sample and then checking an amount of the amplified target nucleic acid.

Abstract: Disclosed is an automatic nucleic acid purification apparatus which can prevent pollution due to aerosol generated from a biological sample containing high concentration target nucleic acid when the biological sample containing the high concentration target nucleic acid is mixed with other biological sample containing low concentration target nucleic acid or not containing the target nucleic acid. Further, disclosed is an automatic nucleic acid purification apparatus which can be applied to all kinds of nucleic acid purification equipments for purifying a plurality of biological samples using a magnet rode or a multi-pipette block moving in two or three axial directions, and which can minimize pollution due to the aerosol generated from the biological sample containing high concentration target nucleic acid and also can obtain accurate results.
