ABSTRACT:
An oligonucleotide comprising a specific region and one or two non-specific regions which are bound to at least one of the two termini of the specific region, wherein the specific region has a specific base sequence which is substantially complementary to a target sequence of a sample nucleic acid with which the oligonucleotide is to be hybridized, the non-specific region is composed of at least one nucleotide having other base capable of forming a base pair with each of bases constituting a common nucleic acid, or its oligomer, is used as a probe for the hybridization.
