US Patent 7718365 Microarray analysis of RNA

In certain embodiments, the invention provides a method of performing an array analysis, the method including contacting a sample of RNA with an analogous DNA set to provide a DNA/RNA duplex, contacting the DNA/RNA duplex with an enzyme having a DNA:RNA nuclease activity to provide a digested RNA sample, and contacting the digested RNA sample with an array under conditions sufficient to provide for specific binding to the array. The array typically is then interrogated. Kits in accordance with the invention are also described which include an analogous DNA set and an array.
