20090143243 | MICROARRAY SYSTEM WITH IMPROVED SEQUENCE SPECIFICITY - 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. | 06-04-2009 |
