    • The present invention relates generally to compositions and methods for use in recombinational cloning of nucleic acid molecules. In particular, the invention relates to nucleic acid molecules encoding one or more recombination sites or portions thereof, to nucleic acid molecules comprising one or more of these recombination site nucleotide sequences and optionally comprising one or more additional physical or functional nucleotide sequences. The invention also relates to vectors comprising the nucleic acid molecules of the invention, to host cells comprising the vectors or nucleic acid molecules of the invention, to methods of producing polypeptides using the nucleic acid molecules of the invention, and to polypeptides encoded by these nucleic acid molecules or produced by the methods of the invention. The invention also relates to antibodies that bind to one or more polypeptides of the invention or epitopes thereof. The invention also relates to the use of these compositions in methods for recombinational cloning of nucleic acids, in vitro and in vivo, to provide chimeric DNA molecules that have particular characteristics and/or DNA segments.

    • Particles such as bacteria may be enumerated from a liquid in an accurate and efficient manner through use of an apparatus including a filter sheet which is oriented transverse to the surface of the liquid being filtered. The filter sheet is so arranged so that, as the liquid is filtered, an increasing portion of the filter is above the surface of the liquid. As a result of the surface of the liquid dropping across the filter, a smaller fraction of the total volume of the liquid passes through the upper portion of the filter than through the lower portion of the filter. Since the number of bacteria trapped per unit area of the filter depends on the volume filtered through the area, a monotonically increasing gradient of density of filtered bacteria occurs from the top to the bottom of the filter.
    • 可以通过使用包括与被过滤的液体的表面横向定向的过滤片的设备,以精确和有效的方式从液体中列举诸如细菌的颗粒。 过滤片被布置成使得当过滤液体时,过滤器的增加部分在液体表面之上。 由于液体表面滴落在过滤器上,液体的总体积的较小部分通过过滤器的上部,而不是通过过滤器的下部。 由于过滤器每单位面积捕获的细菌数量取决于通过该区域过滤的体积,所以从过滤器的顶部到底部发生单调递增的过滤细菌浓度梯度。
