Abstract (en)

[origin: WO03012066A2] The present invention provides methods of performing enzymatic reactions, including PCR, which require the use of magnesium dependent enzymes, including restriction endonucleases, ligases, and reverse transcriptases. The method is based on sequestration of magnesium ions in the form of a precipitate which renders a magnesium dependent enzyme inactive until the appropriate time in the reaction when a certain temperature is reached and the magnesium ions are released from the precipitate. Also provided are kits comprising reagents and instructions for amplifying a target nucleic acid, for DNA digestion and ligation, and for reverse transcription ofRNA into cDNA. Furthermore, the kits and reagents of the present invention can be utilized in other reactions requiring magnesium dependent enzymes.
