Method for obtaining short RNA and kit for same

摘要

Extracting at least a short RNA comprises: providing a biological solution containing short RNA and proteins and/or long nucleic acids, preferably RNA and DNA; separating the proteins and long nucleic acids from the solution, where the proteins are precipitated; adsorbing the short RNA at a solid (first) carrier after precipitating the proteins; and extracting the short RNA by desorption from the carrier. An independent claim is included for a kit for extracting the short RNA comprising at least a solid carrier for adsorption of nucleic acids, protein precipitating reagent, at least one binding substance for selective adsorption of short RNA at a solid carrier, and a manual with procedural steps.
