Abstract: The present invention provides a method for determining whether or not a test sample contains a phytopathogenic oomycete selectively from two kinds of oomycetes of a phytopathogenic oomycete and a non-phytopathogenic oomycete. The method according to the present invention comprises: (a) putting the test sample on a front surface of a cellulose film; wherein the cellulose film has a thickness of not less than 0.5 micrometers and not more than 3.7 micrometers; (b) leaving the test sample at rest for more than 8 hours and not more than 12 hours after the step (a); (c) observing a back surface of the film after the step (b); and (d) determining that the test sample contains the phytopathogenic oomycete, if an oomycete is found on the back surface of the film in the step (c).

Abstract: Provided is a method for determining whether or not a test sample contains a phytopathogenic oomycete selectively from two kinds of oomycetes of a phytopathogenic oomycete and a non-phytopathogenic oomycete. The present method comprises: (a) putting the test sample on a front surface of a film comprising a through-hole having a cross-sectional area of not less than 0.785 square micrometers and not more than 7.065 square micrometers; (b) leaving the test sample at rest after the step (a); (c) observing a back surface of the film after the step (b); and (d) determining that the test sample contains the phytopathogenic oomycete, if an oomycete is found on the back surface of the film in the step (c).

The present method comprises: (a) putting the test sample on a front surface of a film comprising a through-hole having a cross-sectional area of more than 7.065 square micrometers and not more than 19.625 square micrometers; (b) leaving the test sample at rest after the step (a); (c) observing a back surface of the film after the step (b); and (d) determining that the test sample contains the phytopathogenic oomycete, if an oomycete is found on the back surface of the film in the step (c).

Abstract: In order to provide a method for collecting a droplet attached on an external surface of a needle into a capillary tube, the present invention is a method for collecting a droplet attached on an external surface of a needle into a capillary tube, the method comprising steps of: (a) preparing a substrate comprising a capillary tube; a flexible thin film; a liquid-repellent film; and a hole; (b) moving the needle in the Z-direction to move the droplet from the external surface of the needle to the surface of the liquid-repellent film; (c) allowing the droplet to arrive at an inlet of the capillary tube by moving the needle more in the Z-direction, so as to suck the droplet into the capillary tube by a capillary phenomenon.

Abstract: Provided is a method for effectively expressing mouse olfactory receptor Olfr15 on the cell membrane. The method includes steps of: bringing a cell into contact with a culture medium containing chlorpromazine; separating the culture medium from the cell so as to remove the culture medium; and incubating the cell using a culture medium which does not contain chlorpromazine to express the mouse olfactory receptor Olfr15 on the cell membrane.
