| 摘要 |
The invention relates to an RNA-dependent RNA-polymerase, to methods and kits for marking and/or amplifying in a primary dependent or independent manner a ribonucleic acid (RNA), in particular a viral, eucaryontic, procaryontic and double-stranded ribonucleic acid (RNA) for the biological and medical use thereof. Said RNA-dependent RNA-polymerase comprises a right-hand conformation and the amino acid sequence the following sequence sections: a. XXDYS b. GXPSG c. YGDD d. XXYGL e. XXXXFLXRXX having the following significances: D: aspartate, Y: tyrosine, S: serine, G: glycine, P: proline, L: leucine, F: phenylalanine, R: arginine, X: any amino acid. The inventive amplifying method is particularly suitable for microarray engineering, siRNA production and for diagnosticating viral infections by detecting viral RNA in patient samples. The inventive marking method is particularly suitable for purifying RNA by means of affinity bonds and for marking RNA used in molecular biology methods for characterising the function and/or structure of a viral, eucaryontic, procaryontic and double-stranded ribonucleic acid (RNA).
