Patent ID: 7029882

Claim:
A suspension for determining the sequence of genetic materials, wherein suspended in a liquid in a container there is, a first coded oligonucleotide group which includes first coded oligonucleotides having one type of base sequence of a predetermined base number which have been coded by kind or molar ratio of labeled material so as to identify the base sequence thereof, so as to cover the base sequences of all the types or specific types for the base number thereof, and which are each provided so as to be sortable as one belonging to this group, wherein the respective first coded oligonucleotides belonging to said first coded oligonucleotide group comprise an oligonucleotide of one type having a predetermined base sequence and labeled material bonded to said oligonucleotide, and said labeled material includes predetermined kinds thereof at predetermined molar ratios respectively, and the coding is performed by changing the molar ratio of the labeled material, a second coded oligonucleotide group which includes second coded oligonucleotides having one type of base sequence of a predetermined base number which have been coded by kind or molar ratio of labeled material so as to identify the base sequence thereof, so as to cover the base sequences of all the types or specific types for the base number thereof, and which are each provided so as to be sortable as one belonging to this group, and an enzyme which differentially bonds the two coded oligonucleotides via a deoxyribose being a sugar of the end nucleotide thereof, only in the case of a situation where the two coded oligonucleotides are hybridized to a single strand genetic material and the end nucleotides of the base sequence thereof are directly adjacent, and the base sequence of said predetermined base number is a constant relation with the base sequence of that genetic material.
