Compositions and methods related to solid phase sequence detection and genotyping

摘要

The present invention provides improved compositions and methods of sequence detection and single nucleotide (“SNP”) genotyping. The methods of the present invention are related to combining sequence or allelic specific ligation on a solid phase platform with specific and efficient solid phase signal amplification. The methods for sequence detection include a first, second and third oligonucleotide. The methods of SNP genotyping include four oligonucleotides for SNPs associated with two alleles and additional oligonucleotides may be added for SNPs associated with more than two alleles. The usefulness of the present method is that it results in the determination of thousands of genotypes simply, rapidly and inexpensively on a solid support from a single genomic DNA sample.
