弱碱性环境有利于DNA溶解,溶解之后可以很方便的用buffer恢复到所需的pH,比如TRIzol中提DNA的部分就建议DNA沉淀首先在弱NaOH中过夜,待溶解之后再调pH。
Resuspending in weak base is HIGHLY recommended since isolated DNA does not resuspend well in water or in Tris buffers. The pH of the 8 mM NaOH is only ~9 and should be easily adjusted with TE or
HEPES once the DNA is in solution.
