Addressable oligonucleotide array of the rat genome
View Patent ↗The invention provides nucleic acid sequences which are complementary, in one embodiment, to a wide variety of Rat genes. The invention provides the sequences in such a way as to make them available for a variety of analyses. In one embodiment the nucleic acid sequences provided are present as an array of probes that may be used to measure gene expression of at least 20,000 rat genes. As such, the invention relates to diverse fields impacted by the nature of molecular interaction, including chemistry, biology, medicine, and medical diagnostics.
1. An array comprising a plurality of nucleic acid probes, wherein the plurality comprises each of the sequences listed in SEQ ID Nos. 1-699,466, and wherein each probe in the plurality of nucleic acid probes consists of one of the sequences listed in SEQ ID Nos. 1-699,466.
2. The array of claim 1 wherein said plurality of nucleic acid probes is attached to a solid support.
3. The array of claim 1 wherein the array comprises a plurality of beads wherein the probes are attached to the beads and the probes on a bead consist of one of the sequences listed in SEQ ID Nos. 1-699,466.
4. The array of claim 1 wherein the array consists of a single contiguous solid support.
5. A method of monitoring gene expression levels in a biological sample from a rat comprising:
isolating nucleic acid derived from the sample;
labeling the nucleic acid;
hybridizing the labeled nucleic acid to the array of claim 1 ; and,
detecting the hybridization pattern, wherein the intensity of signal resulting from hybridization to probes on the array is used to monitor gene expression levels.
6. The method of claim 5 wherein said monitoring gene expression levels comprises comparing gene expression levels of nucleic acids derived from two or more different samples and further comprises the step of:
comparing said hybridization patterns between said nucleic acid derived from said two or more different samples.
7. The method of claim 5 wherein the labeled nucleic acid hybridized to the array consists essentially of DNA.
8. The method of claim 5 wherein the labeled nucleic acid hybridized to the array consists essentially of RNA that is complementary to target mRNA.
9. The method of claim 5 wherein the labeled nucleic acid hybridized to the array consists essentially of RNA that is in the sense orientation relative to target mRNA.
10. The method of claim 5 wherein the labeled nucleic acid is hybridized to the array in a single reaction.
