    摘要: The present invention relates to methods of using aqueous two-phase system (ATPS) for the isolation, concentration and/or purification of short nucleic acid fragment having about or less than 250 base pairs (bp). In one embodiment, the present invention provides a composition and kit for the purification of short nucleic acid fragments having about or less than 250 base pairs from nucleic acid-containing biological materials. In another embodiment, the present invention provides uses of certain salts and/or polymers in a two-phase system for the purification of short nucleic acid fragments having about or less than 250 base pairs from nucleic acid containing biological materials.

    摘要: The present invention provides a technique for estimating a bacterial concentration from a sample in which bacteria and impurities are mixed, and adjusting the bacterial concentration in the sample to a desired value. An automatic analyzer according to the present invention introduces a substance that destroys impurities into a sample in which bacteria and the impurities are mixed, separates the destroyed impurities and the bacteria, and then takes out the bacteria by a filter, and estimates the concentration of bacteria in the sample according to correspondence data between the amount of impurities remaining on the filter and the concentration of bacteria in the sample. .
