A method for DNA sequencing by hybridization with oligonucleotide matrix.
摘要：
A new technique of DNA sequencing by hybridization with oligonucleotide matrix (SHOM) which could also be applied for DNA mapping and fingerprinting, mutant diagnostics, etc., has been tested in model experiments. A dot matrix was prepared which contained 9 overlapping octanucleotides (8-mers) complementary to a common 17-mer. Each of the 8-mers was immobilized as individual dot in thin layer of polyacrylamide gel fixed on a glass plate. The matrix was hybridized with the 32P-labeled 17-mer and three other 17-mers differing from the first one by a single base change. The hybridization enabled us to distinguish perfect duplexes from those containing mismatches in 32 out of 35 cases. These results are discussed with respect to the applicability of the approach for sequencing.
