The present invention provides improved methods and compositions for RNA isolation. In particular embodiments the present invention concerns the use of methods and compositions for the isolation of full-length RNA from fixed tissue samples. The present invention provides methods for digesting and extracting RNA from a fixed tissue sample. The methods are based on a digestion buffer comprising a polyanion (e.g. citrate) and a protease (e.g. proteinase K). |
