Abstract: Several molecular techniques require high-quality RNA, free from DNA. Various methods have been described to obtain RNA to be used in expression studies or as starting material in differential display-reverse transcriptase (dd-RT-PCR), for which high-quality RNA free from DNA is an essential requirement. In this report, we compare three different methods to isolate RNA from Gram-positive bacteria: (1) An acid-phenol extraction protocol. (2) The "RNeasy mini kit" from QIAGEN (Valencia, CA, USA). (3) The "SV Total RNA Isolation System" from Promega (Madison, WI, USA).The QIAGEN-kit delivers the highest amount of RNA with the highest purity. Slot blot analysis and dd-RT-PCR confirm the absence of DNA contamination and Northern blot analysis and dd-RT-PCR show high quality of the extracted RNA.This RNA extraction method thus addresses current problems by permitting rapid and safe isolation with high yields of intact RNA for subsequent analysis.
