Abstract: Teeth 31 and 32 are formed on opposite sides of a strip portion 2 of a band 1 in the width direction. Protruding portions 51-54 are formed in a proximal portion 20 of the strip portion 2 so as to respectively engage the teeth 31 and 32 on the opposite sides of the strip portion 2 in the width direction. A release portion is provided between the protruding portions 51-54 for allowing a portion of the distal portion 22 and the intermediate portion 21 of the strip portion 2 where the teeth 31 and 32 are formed to be moved into and out of a space between the protruding portions 51-54.

Abstract: Provided is a probe to be used in a DNA microarray having an excellent detection rate of a polymorphism such as SNP contained in genomic DNA. A method for designing a probe according to the invention includes the steps of: specifying one or more regions covering at least a part of fragments flanked by restriction enzyme recognition sites recognized by a restriction enzyme, contained in genomic DNA derived from an organism to be tested; and designing a probe for the specified one or more regions for detecting the fragment in the organism to be tested.
