An array where a selectively hybridizable substance is immobilized, wherein the samples can be distinguished from one another independently of the positional relationship, any array can be produced, the density can be changed according to the method of use, the reaction of a hybridized sample with another sample can be readily detected. A fiber on which a selectively hybridizable substance is immobilized or a fiber array including a bundle of such fibers are disclosed. Further disclosed is a method of hybridization of a selectively hybridizable substance with a corresponding selectively hybridizable substance, which comprises a selectively hybridizing step in which the sample liquid and/or the corresponding selectively hybridizable substance is moved relatively to the surface on which the selectively hybridizable substance is immobilized by a method of, e. g., applying an AC voltage perpendicularly to the normal to the surface on which the selectively hybridizable substance is immobilized. |
