This disclosure relates generally to methods and kits useful for preparing samples, extracting nucleic acids from samples (e.g., biological samples), and/or detecting nucleic acids (e.g., pathogen nucleic acids) in samples (e.g., samples obtained from a subject). In particular, compositions, kits, and methods are provided comprising detergents and proteinases to treat biological samples prior to extraction of nucleic acids. Also described is use of cations for improved efficiency of nucleic acid hybridization. The prepared nucleic acid is suitable for PCR assays including those described for detection of Mycobacterium tuberculosis. |
