pubmed:abstractText |
The efficiency of sequencing by hybridization to an oligonucleotide microchip grows with an increase in the number and in the length of the oligonucleotides; however, such increases raise enormously the complexity of the microchip and decrease the accuracy of hybridization. We have been developing the technique of contiguous stacking hybridization (CSH) to circumvent these shortcomings. Stacking interactions between adjacent bases of two oligonucleotides stabilize their contiguous duplex with DNA. The use of such stacking increases the effective length of microchip oligonucleotides, enhances sequencing accuracy and allows the sequencing of longer DNA. The effects of mismatches, base composition, length and other factors on the stacking are evaluated. Contiguous stacking hybridization of DNA with immobilized 8mers and one or two 5mers labeled with two different fluorescent dyes increases the effective length of sequencing oligonucleotides from 8 to 13 and 18 bases, respectively. The incorporation of all four bases or 5-nitroindole as a universal base into different positions of the 5mers permitted a decrease in the number of additional rounds of hybridization. Contiguous stacking hybridization appears to be a promising approach to significantly increasing the efficiency of sequencing by hybridization.
