[0067] Hereafter, an example of the invention will be described. The invention, however, is not limited to the example.

[0068] (Recovery of Cells from Stool)

[0069] Stool voided by a colorectal cancer patient prior to operation was used as a specimen. As to the use of stool, the subject was informed of the content of the procedure prior to the experiment and a written consent was obtained.

[0070] Two hundred mL of Hanks solution (Nissui) containing 10% FBS was put into a stomacher bag containing stool (about 5 to 80 g) and the bag was then sealed. A stool suspension was then prepared by using a stomacher (200 rpm, 1 min).

[0071] In the case where a stomacher bag having a filter was used, the suspension was filtered by the filter in the bag. In the case where a stomacher bag without a filter was used, the suspension was filtered by passing it through a funnel-shaped filter set on a tubular plastic container. The filtered solution was recovered in a beaker. The filtered solution was furt
