Method for the extraction and purification of nucleic acids on a membrane

摘要

The invention relates to a method for the extraction and detection of nucleic acids on a membrane, making it possible to identify the microorganisms present in low concentration in a liquid or gaseous medium, as well as a novel lysis composition comprising guanidium chloride and between 0.1 and 1% N-Lauroyl-Sarcosine (NLS) making it possible to implement this method.
