    摘要: The present invention relates to a novel method for detection of target nucleic acid sequences on a solid phase using dual-labeled immobilized probes and its resistance to a 5′ to 3′ exonuclease activity of a DNA polymerase. Because the label is remained on the solid substrate by resistance to nucleases due to labeling of a base component the internal nucleotide, the present invention requires no consideration of a suitability of position of the label for remaining on the solid substrate. The present invention ensures to minimize background signal by positioning labels at a site on probes suitable to maximize quenching efficiency of the dual label system, since it permits to freely determine the position of the internal label on probes.

    摘要: The invention provides a novel array method for nucleic acid sequence detection with improved specificity which allows for detection of genetic variation, from simple SNPs (where the variation occurs at a fixed position and is of limited allelic number) to more complex sequence variation patterns (such as with multigene families or multiple genetic strains of an organism where the sequence variation between the individual members is neither fixed nor consistent). The array is comprised of short, synthetic oligonucleotide probes attached to a solid surface which are hybridized to single-stranded targets. Single stranded targets can be produced using a method that employs primers modified on the 5′ end to prohibit degradation by a 5′-exonuclease that is introduced to degrade the unprotected strand. The invention further provides for printing buffers/solutions for the immobilization of oligonucleotide probes to an array surface. The invention also provides hybridization and wash buffers and conditions to maximize hybridization specificity and signal intensity, and reduce hybridization times.
