Patent ID: 11168352

Abstract:
The present disclosure provides a nucleic acid amplification method. The method comprises forming an enrichment culture by contacting a sample with a nutrient medium having a formulation that does not include a phosphate buffer component; holding the enrichment culture for a period of time at a temperature that facilitates growth of a target microorganism; after holding the enrichment culture, forming an aqueous composition by mixing a first volume of the enrichment culture with a second volume of a lysis buffer; contacting the aqueous composition with an effective amount of a water-insoluble material that sequesters a substance that interferes with a polymerase-mediated nucleic acid amplification reaction; subjecting the aqueous composition to a thermal lysis process; and, after subjecting the aqueous composition to the thermal lysis process, subjecting a portion of the aqueous composition to a nucleic acid amplification process. A composition for a lysis buffer is also disclosed.
