Methods of analysis of degraded nucleic acid samples
View Patent ↗The invention provides arrays for analysis of compromised nucleic acid samples, for example, nucleic acids obtained from formalin fixed paraffin embedded samples and methods to analyzed these compromised samples. Arrays are disclosed in which the probe selection region used to select probes for the array is the 300 bases of the target MRNA that are immediately upstream of the start of the poly(A) tail of the mRNA. The probes selected for the array are more biased toward the 3′ end of the mRNA than other arrays that are currently available.
1. An array comprising a plurality of different sequence oligonucleotide probes wherein each different sequence in the plurality consists of one of the sequences in SEQ ID NO: 1-673,904, wherein the plurality of different sequence oligonucleotide probes consists of each of the sequences listed in SEQ ID NO: 1-673,904 and wherein each different sequence is present in a different feature of the array.
2. The array of claim 1 further comprising a plurality of control probe sets.
3. The array of claim 1 wherein the array comprises a plurality of beads or particles each having a single sequence from SEQ ID NO: 1-673,904 attached and wherein the array includes at least one bead having each of the sequences listed in SEQ ID NO: 1-673,904 attached.
4. The array of claim 3 wherein the plurality of beads is associated with a solid support to form an array of beads.
