Abstract
The invention relates to methods for determining sequence information in polynucleotides by combining the recent disparate technologies of mass spectrometry and polynucleotide hybridization, amplification, extension and/or ligation techniques. Broadly, in a first step, the method for determining sequence information in a sample polynucleotide includes hybridizing with a sample nucleotide one or a mixture of oligonucleotide probes having a nucleotide sequence complementary to a portion of the sample polynucleotide, thereby forming a complex. Then, in a second step, the complex is contacted with at least a member selected from the group consisting of nucleosides, dideoxynucleosides, polymerases, nucleases, transcriptases, ligases and restriction enzymes to alter at least a subset of said oligonucleotide probes. In a third step, the method provides for determining the molecular weight of at least the subset of altered probes by mass spectrometry and infering the sequence information of the sample polynucleotide therefrom.
