摘要:
The present invention provides methods modified oligonucleotides and methods of using the modified oligonucleotides for silencing nucleic acids, wherein the nonspecific effects of nucleic acid silencing are reduced.
摘要:
Methods and compositions for extracting nucleic acids from a biological sample are provided. The extraction compositions contain a protease enzyme such as proteinase K at alkaline pH with little or no surfactant present. Extraction can be efficiently performed in 60 minutes or less at room temperature for certain mammalian tissue samples and at elevated temperatures for certain plant tissues.
