Abstract
The present invention is directed to a method of designing a plurality of capture oligonucleotide probes for use on a support to which complementary oligonucleotide probes will hybridize with little mismatch, where the plural capture oligonucleotide probes have melting temperatures within a narrow range. The first step of the method involves providing a first set of a plurality of tetramers of four nucleotides linked together, where (1) each tetramer within the first set differs from all other tetramers in the first set by at least two nucleotide bases, (2) no two tetramers within the first set are complementary to one another, (3) no tetramers within the first set are palindromic or dinucleotide repeats, and (4) no tetramer within the first set has one or less or three or more G or C nucleotides. Groups of 2 to 4 of the tetramers from the first set are linked together to form a collection of multimer units. From the collection of multimer units, all multimer units formed from the same tetramer and all multimer units having a melting temperature in ° C. of less than 4 times the number of tetramers forming a multimer unit are removed to form a modified collection of multimer units. …
