RNA extraction from mammalian tissues.
Purification of intact RNA is the primary step of many molecular biology techniques, including Northern blotting, RNase protection, quantitative polymerase chain reaction, and microarray assays. RNA extraction is typically conducted using either a phenol-chloroform or a solid phase method. This article concentrates primarily on the former approach, which is highly versatile, and is easily adapted to different tissues ranging from whole organs down to submillimeter biopsy punches. The major pr...Expand abstract
