I want to purify RNA from heart tissue. What is the best kit to use?
FAQ ID -3116

For difficult to lyse tissues, the RNeasy Fibrous Tissue Kit is recommended. However, many researchers have had great success purifying RNA from heart tissue using the RNeasy Plus Universal kit.  The QIAzol Lysis Reagent in this kit has shown to be very effective in providing an efficient lysate for RNA purification.
