Abstract: The present invention is based on the discovery of sensitive and specific methylation detection by a) controlling excessive DNA degradation prior to conversion by incubating DNA conversion reagent (e.g. bisulfite reagent) directly with a nucleic acid containing sample without requiring prior nucleic acid purification from the sample and without requiring prior nucleic acid denaturation at elevated temperatures of 98° C. and, b) optimizing bisulfite removal by controlling the pumping rate flow of the bisulfite treated sample over an extraction membrane inside an automated system. In some embodiments, a cartridge for the detection of methylated DNA is provided.
