Theribonucleaseprotectionassay(RPA)
The ribonuclease protection assay (RPA) is a highly sensitive and specific method for the detection of mRNA species. The assay was made possible by the discovery and characterization of DNA-dependant RNA polymerases from the bacteriophages SP6, T7 and T3, and the elucidation of their cognate promoter sequences. These polymerases are ideal for the synthesis of high-specific-activity RNA probes from DNA templates becau......阅读全文
