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.

摘要:
The present invention relates to methods, microarrays and kits for detecting one or more human astrovirus serotypes in a sample (e.g., a fecal sample) from an individual. The method includes amplifying nucleic acid molecules of the sample with one or more primers, to thereby obtain an amplified nucleic acid product; contacting the amplified nucleic acid product with one or more serotype specific probes having a nucleic acid sequence that is specific for only one astrovirus serotype in the group of astroviruses being assessed, wherein the nucleic acid sequence includes between about 9 and 25 nucleic acid bases (e.g., SEQ ID NO: 5-24); and detecting the hybridization complex. The presence of hybridization complexes with a serotype specific probe indicates the presence of one or more specific astrovirus serotypes, and the absence of hybridization complexes with a serotype specific probe indicates the absence of the specific astrovirus serotype. Identification of the astrovirus serotypes allows for one to diagnose an individual infected with the serotype. The present invention further includes microarrays having any one of the astrovirus specific probe, or kits having microarrays and reagents for carrying out the assay.

摘要:
The invention relates to kits and methods for hybridizing nucleic acids with a specific nucleic acid-binding agent, such as a complementary nucleic acid. Previously, others have hybridized a nucleic acid with such an agent bound to a substrate. The improved methods described herein comprise binding a polycationizable attractor compound to the substrate, in addition to the agent. Examples of suitable polycationizable attractor compounds include polypeptides, including those with tunable cationizable amino acid residues, such as histidine. Compositions, kits, devices, and methods that make use of this hybridization rate enhancement technology are disclosed.
