发明名称 REMOVAL OF MOLECULAR ASSAY INTERFERENCES FOR NUCLEIC ACIDS EMPLOYING BUFFERED SOLUTIONS OF CHAOTROPES
摘要 The present disclosure relates to methods, compositions, and systems for reducing and/or eliminating ("suppressing") undesirable effects of a masking agent on a molecular assay. In addition, the present disclosure relates to molecular assays of nucleic acids in bodily fluids and/or excretions. Suppressing undesirable effects of a masking agent may include, according to some embodiments, contacting a test sample with a composition comprising a chelator, a chelator enhancing component, and a buffer. A buffer, in some embodiments, may increase the concentration of chelators and/or chelator enhancing components that may be used without undesirable effects on a nucleic acid of interest (e.g., the integrity of the nucleic acid). In some embodiments, a buffer may enhance suppression of interference from masking agents. The amounts of the chelator(s) and the chelator enhancing component(s) may be selected such that interference of a masking agent on a molecular assay of a nucleic acid-containing test sample are suppressed.
