Kits Take the Trickiness Out of RNA Isolation, Purification

MINIMIZES CONTAMINATION: Ambion’s Rnase Zap destroys Rnase on laboratory surfaces.
RNA is the most versatile biological molecule. It carries genetic information from the nucleus to the cytoplasm, then actively participates in protein synthesis; it also can function catalytically. All cells of a multicellular organism have similar collections of transfer and ribosomal RNAs, but it is the repertoire of messenger RNAs (mRNAs) that sculpts a specialized cell’s identity, expressing the subsets of genes that distinguish bone from muscle, xylem from phloem. So important is RNA that many investigators hypothesize that it played a pivotal role in the origin of life (see Research).

Because RNA lies at the heart of gene expression, extracting it from cells is a common procedure in many cell biology, molecular biology, and biochemistry laboratories. "Obtaining high-quality, intact RNA is the first and often the most critical...
